A growing number of networking experiments outside the United States had already begun to take shape, including two significant projects in France and Great Britain. Louis Pouzin, the computer scientist working for IRIA, was designing a packet-switched network called Cyclades; Donald Davies, the computer scientist at Great Britain’s NPL, had begun his packet-switching experiments in the mid-1960s. Additionally, several PTT national monopolies in Europe were evaluating packet-switching technology, and the European Common Market had asked Derek Barber from Britain’s NPL to direct the creation of a European Informatics Network. These researchers came together to pursue their shared objective: to design new network standards for a new era of digital, packet-switched communication. The network researchers assembled in Washington, D.C. in October 1972 – including Pouzin, Davies, Barber, and leaders of the Arpanet community – took advantage of the unprecedented occasion to form the International Network Working Group (INWG).

By the late 1970s, three competing communities of researchers – Arpanet engineers, telecommunications professionals in the ITU, and a loose alliance of American and European computer professionals – were seeking to establish their own designs as the definitive architecture for packet-switched networks. They would press on with the benefit of Pouzin’s insights but without the presence of the sage of datagrams himself. INWG member John Day summarized the significance of Pouzin’s technical work, suggesting that the conventional wisdom about the “invention” of packet-switching and internetworking is incomplete without reference to Pouzin and the young cohort of computer researchers whom he inspired: The real breakthrough in networking is not packet switching (Baran and Davies independently), but datagram packet switching (Pouzin). I have always found it somewhat interesting that every project Baran and Larry Roberts have been involved in since the ARPANet have been connection-oriented networks, not connectionless ones.

Rather, the principles of openness and consensus have international origins and global consequences. In Chapter 6, I describe a series of international collaborations in the 1970s among American, British, and French computer researchers who tried, and ultimately failed, to agree on a single design for packet-switched computer networks. Instead, the future of computer networking appeared to be on the verge of a battle between IBM’s proprietary System Network Architecture and public data networks based on the X.25 standard produced by the International Telecommunications Union. These foes proved to be too powerful for the packet-switched researchers. In 1976, the packet-switching research community splintered into two groups: one inspired by the French computer scientists Louis Pouzin and Hubert Zimmermann, and the other funded by the American Department of Defense and led by Vinton Cerf and Robert Kahn.

Where Wizards Stay Up Late: The Origins of the Internet by Katie Hafner, Matthew Lyon

It was the first and only time the computers went down. The phone company executives’first reaction was to laugh. “I looked up in pain,” said Metcalfe, “and I caught them smiling, delighted that packet-switching was flaky. This I will never forget. It confirmed for them that circuit-switching technology was here to stay, and this packet-switching stuff was an unreliable toy that would never have much impact in the commercial world, and now they could go home to New Jersey. It was clear to me they were tangled up in the past.” Had they looked beyond the luckless Metcalfe and the failed demo, the AT&T executives would have seen the exuberance in other corners of the room. Not only did packet-switching work but it made wondrous things possible. Some of the most ingenious demonstrations involved English-language conversational programs. These were elaborate programs constructed to engage a user in a verbal dialogue with a machine.

In 1954 Davies won a fellowship to spend a year in the United States; part of that year, he was at MIT. He then returned to England, rose swiftly at the NPL, and in 1966, after describing his pioneering work on packet-switching, he was appointed head of the computer science division. The technical similarity between Davies’ and Baran’s work was striking. Not only were their ideas roughly parallel in concept, but by coincidence they had even chosen the same packet size and data-transmission rate. Independently, Davies also came up with a routing scheme that was adaptive, like Baran’s, but different in detail. There was just one major difference in their approaches. The motivation that led Davies to conceive of a packet-switching network had nothing to do with the military concerns that had driven Baran. Davies simply wanted to create a new public communications network.

Before settling on the word, he asked two linguists from a research team in his lab to confirm that there were cognates in other languages. When they reported back that it was a good choice, he fixed on it. Packet-switching. It was precise, economic, and very British. And it was far easier on the ear than Baran’s “distributed adaptive message block switching.” Davies met Baran for the first time several years later. He told Baran that he had been thoroughly embarrassed to hear of Baran’s work after he had finished his own, and then added, “Well, you may have got there first, but I got the name.” Mapping It Out In December 1966, when Larry Roberts arrived at the Pentagon, he knew Donald Davies from his trip to London the previous year, but didn’t know about Davies’ subsequent work in packet switching. And he had never heard the name Paul Baran. A few years earlier, Roberts had decided that computing was getting old and everything worth doing inside a computer had already been done.

The best description is often attributed to Baran, but I don’t think he ever said it, in fact I’m not sure who did (I got it, appropriately, off the Internet), but it is revealing: "Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computer to another computer until the information arrives at its final destination computer. This was crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator." So there you have it. If you could install a computer at various points in the circuit-switched phone network, it would become a packet-switched network, and would withstand not only broken links, but a full scale nu-cu-ler winter. Still a theory, though. Larry Roberts at MIT proposed a collection of computers hooked together via packet switching, which turned into ARPANET.

Payne eventually would go the entrepreneur route, and form Southampton Photonics Inc. in June 2000, a little late to be funding optical ventures. *** Oddly, WDM brought the communications industry full circle. Phone calls began on a circuit-switched network; you just took the whole voice signal and switched it from one wire to another to complete the call. Then packet switching came in, at first to prevent the vulnerability of a nuclear attack. But then packet switching took off, as the most efficient method to handle voice calls, data packets and the transport of Web pages. Packet switching is entirely electrical - a switch SOFTWARE AND NETWORKS 155 or router looks at the header of each packet and decides where to send it. But now with WDM, we are back to circuits. Going from electrical to optical penalizes both cost and speed. An all-optical network means keeping the signal optical as long as possible, until the very last minute when the information is needed.

One of the issues of the day was the idea that a nuclear blast (I’ve learned never to trust anyone that pronounces it nu-cu-ler) would wipe out the phone network and all communications lines and disable the command and control structure of U.S. defense. The president could order a launch, but if no one could get the message, what would be the use? In 1961, Leonard Kleinrock at MIT proposed a PhD thesis called “Information Flow in Large Communication Nets,” and this provided the theory and proof for packet switching, although it wasn’t called packet switching, not yet, and it was still a theory. The North American Aerospace Defense Command or NORAD was in charge of early warning and control. It didn’t want no stinking 144 HOW WE GOT HERE theories, it wanted something it could use. NORAD was nervous about being out of touch, especially with its command center dug into the mountains near Cheyenne. So the Air Force sprinkled money around for research on ways to resolve the vulnerability of communications networks, which were dependant on centralized phone switches.

How Not to Network a Nation: The Uneasy History of the Soviet Internet (Information Policy) by Benjamin Peters

The result of Baran’s conversations was packet switching, a technology that broke messages into “packets,” which allowed digital “bursts” of data to be rerouted around damaged parts of a network—just as the brain can reroute neural impulses around damaged neural matter. Similarly, Baran’s observation was that, due to network effects, the brilliance of a distributed network, whether neural or national, is that it does not need each of the average eighty-six billion neurons in the human brain to connect to every other (and the number of possible connections between eighty-six billion neurons is so incomprehensibly large that the need for robust reconnection becomes obvious).42 Rather, attaching to a couple of other nodes allows a distributed packet-switched network to reroute in real time around damaged territory, whether neural or national.

With no such “competent organization” in sight and after spending six years aggressively publishing his network research internationally to ensure maximum circulation about how survivable communication networks could help ensure mutual deterrence, Baran despaired at the local prospects and turned his attention elsewhere.43 The popularity of the phrase packet switching, which was Davies’s term, and the obscurity of Baran’s initial coinage block switching are evidence that it took outside competition to spur local authorities to take packet switching seriously. The U.S. ARPANET, despite the efforts of its own network entrepreneurs, was inspired by foreign founders. To the degree that Stigler’s law of eponymy holds—“no scientific discovery is named after its original discoverer” (a law that Stigler attributes with a grin to Robert Merton)—Baran’s case rehearses not the exception but the rule that international communication networks precede national computer networks.

Perhaps the cardinal mistake of the socialist imagination of technology is not to dream the celebrated dream of social justice but to bulldoze the rutted world of human relations with the private interest logics of the oikos (military, corporations, states, and individuals that seek only their own survival). The Soviet OGAS figured out the “why?” (socialist utopia) but not the “how?” for their large computer network projects, and researchers at the U.S. ARPANET knew the “how?” (packet-switching networks) but not the “why?” of modern networking. The Soviets’ missing “how?” lasted for the duration of the project, and the absence of the Western “why?” remains both its historical attraction and the contemporary challenge to computer network culture. The Western network “how?” has sped many unfinished attempts at answering the network “why?” The technical openness of packet-switching networks to diverse actors has afforded the Internet astonishing and well-documented successes of technical energy, commercial innovation, and cultural creativity. At the same time, the open-ended “why?”

All the switches in the world could never keep up. But with packet-switched data communications, collective computation scales gracefully as the number of processors (both electronic and biological) grows. Thanks to “hot-potato” routing algorithms, individual messages—the raw material from which intelligence is formed—are broken into smaller pieces, told where they are going but not how to get there, and reassembled after finding their own way to the destination address. Consensual protocols, running on all the processors in the net, maintain the appearance of robust connections between all the elements at once. The resulting free market for information and computational resources determines which connection pathways will be strengthened and which languish or die out. By the introduction of packet switching on an epidemic scale, the computational landscape is infiltrated by virtual circuitry, cultivating a haphazard, dendritic architecture reminiscent more of nature’s design than of our own.

We see the wires plugged into the wall and think of the architecture as constrained by the hardwired topology that the physical connection represents, whereas computationally, our machines belong to a diffuse, untethered cloud of the kind that Good envisioned as the basis of an ultraintelligent machine. All our networking protocols—packet switching, token ring, Ethernet, time-division multiplexing, asynchronous transfer mode, and so on—are simply a way of allowing hundreds of millions of individual processors to tune selectively to each others’ signals, free of interference, as they wish. Paul Baran, pioneer of packet switching, sees the relations between computers and communications advancing along similar, wireless lines. You can plug only so many things at one time into your wall. As everything from taxicabs to telephones to televisions to personal digital assistants becomes connected to the network, universal—and microminiature—wireless is the only way to disentangle the communications web.

Baran founded Com21, Inc., in 1991 to develop the ultrafast packet switches and strategic alliances necessary to deliver a broadband digital communication spectrum over coaxial cable to the home, with a fiber-optic backbone linking the head ends of the local tails. Among the various schemes offering to provide broadband network growth, hybrid fiber-coaxial offers the path of least resistance because much of the infrastructure already is in place. What to do with all this bandwidth is a different problem, but history has shown that as bandwidth becomes available, the digital ecology swiftly takes root and grows. Baran also founded (in 1985) a company named Metricom, better known by the name of its wireless network, Ricochet. A wireless, packet-switched, spread-spectrum digital communications network, Ricochet takes an extreme grassroots approach.

But from a packet-switching point of view, the phone wires are just a means to an end; the sender and receiver don’t actually care how the packets get delivered. The ability to operate agnostically over any number of diverse media would be packet switching’s great virtue. After early networks in the late ’60s and early ’70s, such as the ARPANET, proved the viability of the concept, networks of all types began sprouting across the country, doing packet switching not only over copper phone wires, but over satellites and over radio. In 2001, a group of computer scientists in the Norwegian city of Bergen briefly even implemented a packet-switching network over “Avian Carriers”—that is, packets written down on paper and tied to pigeons’ feet. Of course, packet switching would not be without its own problems. For starters, one of the first questions for any protocol, human or machine, is, quite simply: how do you know your messages are getting through?

“utter heresy”: Jacobson, “A New Way to Look at Networking.” “So little boy went away”: Kleinrock, “Computing Conversations.” would become known as packet switching: The term “packet switching” comes from Donald W. Davies of the National Physical Laboratory, another key contributor to packet switching research at the time. “a consensual illusion between the two endpoints”: Stuart Cheshire, personal interview, February 26, 2015. communications could survive a nuclear attack: Baran, “On Distributed Communications.” a growing network becomes a virtue: For elaboration on this point, and a broader reflection on the history of networking (including its current problems), see Jacobson, “A New Way to Look at Networking.” a packet-switching network over “Avian Carriers”: See Waitzman, A Standard for the Transmission of IP Datagrams on Avian Carriers, Waitzman, IP Over Avian Carriers with Quality of Service, and Carpenter and Hinden, Adaptation of RFC 1149 for IPv6 for descriptions of the avian protocol, and see for details of the actual implementation performed in Bergen, Norway, on April 28, 2001.

In circuit-switched networks, a call fails if any one of its links gets disrupted—which means that reliability goes down exponentially as a network grows larger. In packet switching, on the other hand, the proliferation of paths in a growing network becomes a virtue: there are now that many more ways for data to flow, so the reliability of the network increases exponentially with its size. Still, as Van Jacobson tells it, even after packet switching was devised, the phone companies were unimpressed. “All the telco people said, with very loud voices, that’s not a network! That’s just a crummy way to use our network! You’re taking our wires, you’re sending on the paths that we create! And you’re putting a lot of extra gunk on it so that you use it really inefficiently.” But from a packet-switching point of view, the phone wires are just a means to an end; the sender and receiver don’t actually care how the packets get delivered.

The Dream Machine: J.C.R. Licklider and the Revolution That Made Computing Personal by M. Mitchell Waldrop

Davies's name for the scheme as a whole was "packet switching." From there, said Scantlebury, Davies and his group at Teddington had con- tinued to develop the packet-switching idea with computer simulations. They had even scraped together enough money to build a "one-node" network, con- sisting of a single Honeywell computer connected to a lot of terminals through a special interface. It wasn't much, admittedly. But it did demonstrate the switch- ing principle: you could type in text on one terminal and have it print out on any other terminal you specified. And that, explained Scantlebury, was the sad part of the story: the powers- that-be at the British Postal Service, which had absolute control over the U.K. telecommunications system, had flatly refused to fund Davies's vision of nation- wide packet switching. They couldn't even see the point of a demonstration.

The ICCC demonstration did what it was intended to do, which was make the world sit up and take notice of packet switching. It was what Metcalfe calls the Arpanet's debut-its coming-out party, its coming of age. "Up until that point you couldn't see it anywhere," says Kahn. "All you could do was read an arbitrary abstract paper somewhere that said, 'Here is this new way to do computer communications.' But ICCC was the watershed event that made people suddenly realize that packet switching was a real technology." DIASPORA Looking back on it, there were any number of ways that the Arpanet project could have failed. It could have been snuffed out by the Vietnam-era budget crunch before it even got started, as Pentagon officials scrounged for money high and low. It could have been crushed by the mainstream telecommunica- tions community, which saw packet switching as utterly wrongheaded at best 330 THE DREAM MACHINE and a competitor at worst.

Conversely, a commander in chief blessed with survivable com- mand and control could afford to wait it out, see what developed, and make some effort at a measured response. Indeed, Baran and his colleagues even advocated sharing the packet- switching technology with the Soviets, on the grounds that having survivable communica- tions on both sides would be the most stable configuration of all. THE INTERGALACTIC NETWORK 277 could see that the essence of Baran's network-packets, a decentralized architec- ture, computer routing-was the same as his. So why hadn't Baran's plan been adopted already? Because it was too far ahead of its time, apparently. AT&T engineers, most of whom had spent a life- time perfecting their circuit-switching network, found Baran's packet-switching concept ludicrous ("Son," Baran remembers one telling him with exaggerated patience, "this is how a telephone works. . ."). Worse, Pentagon politics dic- tated that the network would have had to be implemented by the newly orga- nized Defense Communications Agency, which was also staffed by old-line telephone engineers and which simply did not have the technical competence to pull it off.

Larry Roberts at MIT proposed a collection of computers hooked together via packet switching.” “OK. But who invented packets?” I asked. “Paul Baran at Rand in Santa Monica gets a lot of credit for packets.” I know about Rand. It is a Santa Monica, California, think tank spun out of Douglas Aircraft after World War II. It’s still around. Packet Racket 185 “NORAD, you know, the North American Air Defense Command,” Kleinrock continued, “shoehorned in that mountain in Cheyenne, was worried about getting cut off from Washington, so the Air Force commissioned a study on how to resolve the vulnerability of communications networks. Baran wrote a paper in 1964 called ‘On Distributed Computing.’ It’s on the Web. You can find it.” “So that was the start of packet switching.” “Sort of. Baran describes standard message blocks and store and forward transmissions and hot potato routing.

The best description I’ve read goes something like this: “Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computer to another computer until the information arrives at its final destination computer. This is crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator.” “So how did you get involved?” I asked. “Well, my thesis proposal at MIT back in 1961 was called ‘Information Flow in Large Communication Nets.’ So they got me involved,” Eddie, I mean Leonard, answered. “So, wait, 1961. It was you that invented packet switching.” “It was a lot of us.” “But what happened in 1969?” “Oh, right.

That is one of those six nine’s, or four to the right of the decimal point, or 99.9999% reliability. As the story goes, researcher Bob Metcalfe was in the middle of demonstrating the packet network when, like any good demo, it crashed. This put smiles on the faces of those 10 AT&T execu-humps, and they merrily skipped back to headquarters singing the stillbirth of packet switching. Of course, they were right for another 30 years, but packet switching would eventually be trouble for circuit-switched phone networks. Metcalfe got back at them. With the success of its new packet network, ARPA became “D for Defense” DARPA, to remind everyone it was your defense dollars at work, keeping communications alive in the event of a nuclear war. Bob Metcalfe moved from DARPA to the Xerox Palo Alto Research Center. He was playing around with a bunch of new Xerox Alto workstations, trying to devise a fast network both to hook them together, and more importantly, to connect them to laser printers that Xerox was hoping to sell in large numbers.

Taylor drew up a detailed plan for the network, proposing that it use a promising new theoretical approach called “packet switching.” Instead of connecting all the machines on the network directly to each other with leased across time and space and the do lines, this involved breaking data down into small, uniform “packets” that could be passed from one machine to another until they reached the appropriate destination. A computer could then talk to a distant machine via several intermediaries, without needing a direct connection. This approach would greatly reduce the number of leased lines needed to interconnect a given number of computers, and would also make efficient use of network capacity by interleaving traffic between multiple sources and destinations. Packet switching was originally proposed as a way to build networks that would keep working in the event of a nuclear attack, because when part of a packet-switching network is disabled, packets can simply be routed around the problem, finding another path to their destination.

Packet switching was originally proposed as a way to build networks that would keep working in the event of a nuclear attack, because when part of a packet-switching network is disabled, packets can simply be routed around the problem, finding another path to their destination. But given the cost and unreliability of network links and computer hardware in the 1960s, computer scientists realized that packet switching was also a good way to build reliable networks for general use. Taylor invited one hundred and forty companies to bid for the contract to build special interface boxes, called “Interface Message Processors” (IMPs), which would be plugged into computers at different sites and linked up by leased lines. Industry giants IBM, the biggest provider of mainframes, and AT&T, America’s telecoms monopoly, declined to bid. Rather than interconnecting and sharing separate computers, IBM imagined a future of ever-larger mainframes, with remote terminals connected by AT&T’s lines, as the best way to bring many users together.

By early December they had both been linked to a third IMP at the University of California, Santa Barbara, and the Stanford IMP had been connected to the fourth IMP at the University of Utah. The packet-switching system meant that users at each of the four sites could access any of the four connected computers, even when there was not a direct link between their carried out in thIQrespective IMPs. (Network traffic between UCLA and the University of Utah, for example, traveled via Stanford or Santa Barbara.) ARPANET was extended to the east coast in March 1970 and continued to grow as more computers, connected by more IMPs, were added to the network. In 1975, when ARPANET was declared fully operational, rather than being an experimental project, there were 57 IMPs, including one across the Atlantic in London. By 1981 there were 213 computers attached to the network, with another being added, on average, every twenty days. In January 1983 the packet-switching protocol used by the IMPs, known as NCP, was retired in favor of a more robust standard called TCP/IP, which had been developed by Robert E.

“The launching of the sputniks told us,” wrote John Dunning for The New York Times Introduction 4 ration decided to create a computer network that was independent of centralized command and control, and would thus be able to withstand a nuclear attack that targets such centralized hubs. In August 1964, he published an eleven-volume memorandum for the Rand Corporation outlining his research.6 Baran’s network was based on a technology called packet-switching7 that allows messages to break themselves apart into small fragments. Each fragment, or packet, is able to find its own way to its destination. Once there, the packets reassemble to create the original message. In 1969, the Advanced Research Projects Agency (ARPA) at the U.S. Department of Defense started the ARPAnet, the first network to use Baran’s packet-switching technology. The ARPAnet allowed academics to share resources and transfer files. In its early years, the ARPAnet (later renamed DARPAnet) existed unnoticed by the outside world, with only a few hundred participating computers, or “hosts.”

If we are indeed living in a post-industrial, postmodern, postdemocratic society, how does one account for political agency in situations in which agency appears to be either caught in networks of power or distributed across multiple agencies? By looking closely and carefully at the technical specifications of TCP/IP and DNS, Protocol suggests that power relations are in the process of being transformed in a way that is resonant with the flexibility and constraints of information technology. The Internet is not simply “open” or “closed” but above all a form that is modulated. The very concept of packet-switching demonstrates this on several levels, from the efficiency standards of routing during a download, to the ways in which each individual datagram is tagged for delivery to your email account or hard drive. Information does flow, but it does so in a highly regulated manner. This dual property (regulated flow) is central to Protocol’s analysis of the Internet as a political technology. Isomorphic Biopolitics As a final comment, it is worthwhile to note that the concept of “protocol” is related to a biopolitical production, a production of the possibility for experience in control societies.

The term protocol is most known today in its military context, as a method of correct behavior under a given chain of command. On the Internet, the meaning of protocol is slightly different. In fact, the reason why the Internet would withstand nuclear attack is precisely because its internal protocols are the enemy of bureaucracy, of rigid hierarchy, and of centralization. As I show in this chapter, the material substrate of network protocols is highly flexible, distributed, and resistive of hierarchy. The packet-switching technologies behind the Internet provided a very different “solution” to nuclear attack than did common military protocol during the Cold War. For example, in 1958 the Royal Canadian Air Force and the U.S. Air Force entered into agreement under the North American Aerospace Defense Command (NORAD). NORAD is a radar surveillance system ringing North America that provides early warnings of missile or other air attacks against Canada and the United States.

The third problem Roberts faced was how to link together all the computer systems, which came from different manufacturers and used many varieties of operating software that had taken several years to develop. Enough was known about the software crisis at this stage to want to avoid the extensive rewriting of operating systems. Unknown to Roberts, a solution to the first two problems had already been invented. Known as “store-and-forward packet switching,” the idea was first put forward by Paul Baran of the RAND Corporation in 1961 and was independently reinvented in 1965 at the National Physical Laboratory in England by Donald Davies, who coined the term packet switching. Davies recognized the packet-switching concept to be similar to an older telegraph technology. In telegraph networks, engineers had already solved the problem of how to avoid having every city connected to every other. Connectivity was achieved by using a number of switching centers located in major cities.

In the 1930s these manual switching centers were mechanized in “torn-tape offices,” where incoming messages were automatically recorded on perforated paper tape and then retransmitted mechanically. In the 1960s the same functions were being computerized using disk stores instead of paper tape as the storage medium. Store-and-forward packet switching was a simple elaboration of these old telegraph ideas. Instead of having every computer connected to every other, store-and-forward technology would be used to route messages through the network; there would be a single “backbone” communications line that connected the computers together, with other connections being added as the need arose. Packet-switching technology addressed the problem of making economic use of the high-speed communications lines. So that a single user did not monopolize a line, data would be shuttled around the network in packets. A packet was rather like a short telegram, with each packet having the address of the destination.

The computers that acted as the switching centers—called nodes in the Arpanet—would simply receive packets and pass them along to the next node on the route toward the destination. The computer at the destination would be responsible for reconstituting the original message from the packets. In effect, by enabling many users to share a communications line simultaneously, packet switching did for telecommunications what time-sharing had done for computing. All of this was unknown to Roberts until he attended an international meeting of computer network researchers in Gatlinburg, Tennessee, in October 1967. There he learned of the packet-switching concept from one of Donald Davies’s English colleagues. He later described this as a kind of revelation: “Suddenly I learned how to route packets.” The final problem that remained for Roberts was how to avoid the horrendous software problems of getting the different computers to handle the network traffic.

Masters of Deception: The Gang That Ruled Cyberspace by Michelle Slatalla, Joshua Quittner

It's the talk of the hacker elite: Phiber Optik got into a feud with Erik Bloodaxe, and to hear Erik Bloodaxe tell it, Phiber Optik lost. Here's how it happened. One day in 1989, while Chris is working on his big hacker project, a directory of the computers on a large data network known as Telenet, the phone rings. The caller is LOD member Mark Abene, up in New York City. Mark is really upset. His account on the NYNEX Packet Switched Network was killed. Can you imagine? Phiber Optik without access to the NYNEX Packet Switched Network. It was like James Dean without a motorcycle. Mark desperately wants to get back in the system, and knows that Chris has a secret route to the computer. Mark asks for it. Now, Chris knows Mark has access to a list of addresses of certain phone company computers that you can reach over Telenet, Chris wants to include those addresses in his directory.

He's intuitively hacking out the most complex programs and commands you can imagine. He's learning new things, going new places every day. By himself. He's the dude. The funny thing about Phiber is, he's so far into the phone system that when he wants to hit a switch, he does it the hard way. He doesn't just dial the switch in question and connect. No, he logs in through something called the NYNEX Packet Switched Network. This network of computers is much more potent than any single switch. In fact, this network ties together every switch in the New York-New England telephone region. Each is one pearl on the necklace and Phiber has his hands on the clasp. But, ironically, he has never possessed a single specific phone number for any one of the switches. Of course, he hasn't exactly been lusting for one.

As they log into the Laurelton switch to start exploring, he describes every command they're typing even the commands they already know in precise, easy-tounderstand language. He knows everything. And Mark is just as excited by this session as they are, because he senses that finally he's met two other hackers who can ride at his pace. For his part, Mark will always think of this evening as "a meeting of the minds. " They forgot who they were, and where they were, and thought only about where they were headed. Mark has shown them how to use the NYNEX Packet Switched Network to jump off into other switches as well, and tonight they traipse around in the Hollis switch system for a while. In earlier phone conversations, Mark has told them different ways he's found to get into phone company computers, and Paul took it all in. So tonight Mark never has to repeat a phone number, never has to explain the meaning of a command to Paul. Mark types it and Paul absorbs it, because the progression of commands on the monitor is distinctly logical.

Davies, a colleague of Scantleburry's at NPL, in a seminar on time-sharing at MIT in 1965 and had discussed with him and Licklider "networking and the inadequacy of data communication facilities for both time-sharing and networking" (Roberts 1988, 144). After Scantleburry's presentation, Roberts had a discussion with him and considered his suggestion that "packet switching offered a solution to his problem" (Norberg and O'Neill 1996, 166). After his return to Washing- ton, Roberts read Baran's reports on packet switching and initiated contact with him. S In June 1968, Roberts described the ARPANET as a demonstration of the kind of distributed network recommended by Baran in his study. During the winter and spring of 1968, Roberts contracted Elmer Shapiro at SRI, who was only distantly associated with the ARC laboratory, to study the "design and specifications of a computer network."

And finally, the stand-alone workstations of the pre- vious phase are connected into a network. Such a way to describe the evolution of computing focuses on the specific characteristics of the computer at a given time and usually puts the emphasis on a technological innovation that allowed the passage from one phase to the next: the time-sharing operating system, for example, the desktop meta phor of the human-computer interface, or packet switching network technologies. 1 While these innovations obviously contributed greatly to shaping the history of computing, the dynamic of personalization that characterizes the evolution of computing since the late 1940'S played an equally important role. I describe the progressive construction of the user as a person, or, what sometimes amounted to the same thing, how the computer eventually got a personality.

Licklider proposed a network linking the IPTO contractor sites, the main purpose of the network was to be resource sharing, since Licklider and Taylor were concerned about the costs of the multiplication of the infrastruc- ture investments funded by their office (Norberg and O'Neill 1996, 163). This contradicts the often-stated myth of its origin that claims the u.s. Department of Defense wanted a computer network reliable and robust enough to survive a nuclear attack. The effort to achieve the efficiencies of resource sharing drew on technology that made it possible to carry data on leased dedicated phone lines. That technology was packet switching. Robert Taylor had enrolled Larry Roberts to take charge of the ARPANET project, and Roberts started at the IPTO in December 1966, as Taylor's assis- tant director. At the IPTO contractors' meeting at the University of Michigan in Ann Arbor in April 1967, Wes Clark had proposed to organize the network around small computers interfacing the main computer at each site to the com- munication network (Salus 1995,20-21; Hafner and Lyon 1996,72-74).

In the early 1960s, American computer scientist Leonard Kleinrock of the Massachusetts Institute of Technology and Paul Baran of the Rand Corporation, and, later, Britain’s Donald Davies, a physician at the UK’s National Physical Library in Teddington, independently conceived of the same way to send data around a telephone network efficiently by splitting it into chunks and routing it through nodes around the network to later arrive, reassembled, in the right place. These deliberate first steps towards cyberspace had a greater impact on the history of mankind than the simple stroll on a rock high above our heads two years later. This ‘packet-switching’ concept was to become the central structure in international telecommunications and, later, data networks. Four months after the moon landing, on 29 October 1969, the Advanced Research Projects Agency Network (ARPANET), the world’s first packet-switching data network, consisting of four computers in separate university sites, jumped into life. The first message ever sent was meant to say ‘login’, but the system crashed, and the first word ever sent from one computer to another was the accidentally portentous ‘Lo’.

ARPANET is often described as the birth of the internet, and is equally often reported to have been designed to survive a thermonuclear strike, meaning that if one node or cell of the network were destroyed, the others would gather the digital slack and reroute the information around the surviving nodes. However, the aim of ARPANET was not to preserve national security in the event of warfare, but to allow university researchers separated by geography to share information; the net’s roots were indisputably collaborative and altruistic. Its technological cornerstone – the packet-switching network – underpinned all the later digital developments that would enable the reeling madness and quotidian mundanity that comprises a day online today – a day that includes buying groceries, paying bills, sharing photos and ideas, updating the world on your latest hairstyle choices, and, for many more people than is currently acknowledged, talking about and buying drugs. Few involved in the early days of the internet could ever have imagined how central to billions of people’s lives it was to become, but some of them dreamed of it.

Wikipedia soon became an essential resource for those looking for information about new drugs, and the site started publishing entries on the drugs along with their Chemical Abstracts Service (CAS) numbers – the unique identifying code that serves as a chemical Dewey Decimal system. With this information, would-be vendors or users could easily find chemical firms that carried the compounds they wanted. In 2003 MySpace opened the web to a whole generation of teenagers, to whom the concepts of packet-switching were as alien as the concept of not using the net as their first port of call for entertainment or communication. The site, with its super-vernacular design, clumsy layouts and clashing colours, was as riotous and impenetrable as any poster-adorned bedroom wall of previous eras. It wasn’t until late 2004 that the phrase Web 2.0 was officially coined by technologist Tim O’Reilly, who correctly identified the future of the web – it would become a model driven by user-generated content, mass collaboration, global sharing and cross-border participation.2 That year, The Facebook, a web version of the college yearbook popular at American universities, launched.

So Baran expected a friendly reception. After all, he’d be telling a bunch of men with a uranium death sentence that he’d found a way to get them off the Soviet target plan. His new “mesh” network would mean that bombing AT&T would be largely pointless. It wouldn’t blind U.S. commanders. If only they’d redesign their network, the AT&T engineers might save their own lives. They thought he was insane. “I tried to explain packet switching to a senior telephone company executive. In midsentence he interrupted me,” Baran recalled. “The old analog engineer looked stunned. He looked at his colleagues in the room while his eyeballs rolled up, sending a signal of his utter disbelief. He paused for a while, and then said, ‘Son, here’s how a telephone works.’” Of course Paul Baran knew how a telephone worked. You jacked one point to a switch to another point.

Other scientists had been chasing the idea as well, but the design suited Baran’s problem particularly well: a network with no central control, survivable, uncuttable. The earliest large network built on Baran’s principles became known as ARPANET, the Advanced Research Projects Agency Network—a mesh of connections that even today serves as the backbone for parts of the Internet. Even with the risk of nuclear war hopefully long gone, packet-switching designs of one sort or another still account for most of the data moving in the world. Think of how true an idea must be to endure more than fifty years of technological change. And all the efficiencies Baran first predicted fifty years ago are still at work. Every time you make a call, share a video, or ask a machine to think for you, that transaction likely takes place through fishnet-routed packets.

Data flows could be monitored with the ease of watching a subway turnstile. The far-flung, wild creativity of our plug-and-play, connected world would be stifled. Each additional connection to the system would demand bureaucratic, centralized approval by the Switch Despots, concerned more with their own power than with our survival. Instead we have a slice-resistant mesh that has grown a billion times over, with its original architecture largely intact. Packet-switched systems such as the Internet give anyone with some string and an ability to tie knots (which, in techno-speak, is anyone with some blinking fiber-optic cables and a TCP/IP connection) the power to weave themselves into the global web. This is why you can so easily turn on your phone or tablet and more or less instantly touch a whole world of data. Every minute now, an additional ten thousand devices get connected to the Internet—not just wired citizens, smartphones, laptops, and tablets but also medical tools, Bitcoin mines, and airplane diagnostic systems.

A few years later, the Welsh computer scientist Donald Davies hit upon a similar scheme, independent of Baran. He anointed the message fragments with the slightly more Anglo name of “packets,” and the general approach “packet switching.” The metaphors stuck. Today, the vast majority of data circling around the globe comes in the form of message fragments that we still call packets. Years after both Baran and Davies had published their seminal papers, Davies jokingly said to Baran, “Well, you may have got there first, but I got the name.” In the late 1960s, packet switching became the foundation of ARPANET, the research network that laid the groundwork for the Internet. The ARPANET design relied on several radical principles that broke with existing computing paradigms. ARPANET was what we would now call a peer-to-peer network, as opposed to a client-server or mainframe-terminal network.

The second revolutionary aspect of Baran’s survivable system was its method for communicating information from computer to computer. Rather than sending a single message, Baran’s new system broke up this content into many digital pieces, flooding the network with what he called “message blocks,” which would travel arbitrarily across its many nodes and be reassembled by the receiving computer into readable form. Coined as “packet switching” by Donald Davies, a government-funded information scientist at Britain’s National Physical Laboratory, who had serendipitously been working on a remarkably similar set of ideas, the technology was driven by a process Baran called “hot potato routing,” which rapidly sent packets of information from node to node, guaranteeing the security of the message from spies. “We shape our tools and thereafter our tools shape us,” McLuhan said.

We already know how to do it,” Taylor promised. “Great idea,” Herzfeld said. “Get it going. You’ve got a million dollars more in your budget right now. Go.”30 And Taylor did indeed get it going. He assembled a team of engineers including Paul Baran and Wesley Clark, the programmer who had gotten J. C. R. Licklider hooked on the TX-2 computer back in the fifties. Relying on Baran’s distributed packet-switching technology, the team developed a plan to develop a trial network of four sites—UCLA, Stanford Research Institute (SRI), the University of Utah, and the University of California, Santa Barbara. They were linked together by something called an Interface Message Processor (IMP), which today we call routers—those little boxes with blinking lights that connect up the networked devices in our homes.

“Not true,” Taylor interrupted, insisting that the “Internet’s roots” lay with the ARPANET.31 Both Taylor and Kahn are, in a sense, correct. The Internet would never have been built without ARPANET. Growing from its four original IMPs in 1969, it reached 29 by 1972, 57 by 1975, and 213 IMPs by 1981 before it was shut down and replaced as the Internet’s backbone by the National Science Foundation Network (NSFNET) in 1985. But the problem was that ARPANET’s success led to the creation of other packet-switching networks—such as the commercial TELENET, the French CYCLADES, the radio-based PRNET, and the satellite network SATNET—which complicated internetworked communication. So Kahn was right. ARPANET wasn’t the Internet. And he was right, too, about TCP/IP, the two protocols that finally realized Licklider’s dream of an intergalactic computer network. Bob Kahn and Vint Cerf met at UCLA in 1970 while working on the ARPANET project.

The standards wars of this era divided phone companies, which preferred a system that would support discrete circuits between one sender and receiver, like older telephony networks, versus many computing companies, such as IBM, which lobbied hard for packet switching technologies that could treat all messages (e.g., voice, data, image) as recombinant bits flowing over whatever future hardware that could connect with the network. The models of communication (equally technical and social) posed by both options contain profound downstream implications for the geopolitics of an information society. A polity of circuits and a polity of packets are in epistemological and functional opposition. For the circuit model, its stack is a bounded utility for which use is metered by monopolistic caretakers who, by guaranteeing the circuit between sender and receiver, retain de facto sovereignty over the channel. For the packet switching model, at least in the minds of Cerf's group, the platform would prioritize the edges of the network, asking them to do more of the work to reassemble transmitted packets and calculate the content of messages.

We appreciate the role of railroads, telegraphy, and telephony networks as the infrastructure of globalization, and their speed for the acceleration of the modernities of space and time, but perhaps we underappreciate the metastructuring importance of mundane anonymous standards to turn isolated mechanical inventions into infrastructural innovations (e.g., railroad gauges and spike lengths, timetable templates, the semiotics of graphical interface feedback conventions, transmission line materials, arbitrary telegraphic languages, packet-switching protocols, country codes and area codes, the fixed numeration of money itself, and so on). The centrifugal standardization of how individual components interrelate and assemble into higher-order systems, whether physical or informational, is as important as what any part or component may be. This is how platforms can scale up. To engineer systems that coordinate the shuttling of units from one point to another with efficiency, adaptability, and flexibility is to compose within the rules laid down by other systems, larger and smaller, with which interaction is required.

For example, the formal urban grid in a major city is for the most part rigid and inflexible, but precisely because of this linear and universally authoritarian topography, it affords both maximum tumult of dynamic horizontal interchange in the street plan as well as vertical recombinant programmatic complexity in the skyscrapers that pop up in each of its cells (more on this in the City layer chapter).8 Similarly, it is the legal and practical standard size of the humble paper envelope that makes it possible for it to shuttle messages both discrete and discreet; like the urban grid, the envelope's power is in its dumbness. In the 1970s as the world's cities began to more fully merge into the networked hierarchies of today with the widespread standardization of very-large-scale envelopes, made of steel instead of paper, in the form of fixed proportion and attribute shipping containers. Containerization migrated the packet switching from telecommunications onto the transit of physical objects (or perhaps the other way around). It traded the standardized, linear traffic program of the grounded asphalt grid for another, now smoothed into liquid shipping lanes, pacing big packets of objects back and forth across the avenues of oceans. 10.  How Platforms Work Platforms centralize and decentralize at once, drawing many actors into a common infrastructure.

Furthermore, the extraordinary increase of transmission capacity with broadband communication technology provided the opportunity to use the Internet, or Internet-related communication technologies, to transmit voice, as well as data, through packet switching, thus revolutionizing telecommunications – and the telecommunications industry. According to Vinton Cerf, “Today you go through a circuit switch to get a packet switch. Tomorrow you’ll go through a packet switch to get a circuit switch.”55 In another technological vision, Cerf asserted that “during the latter half of the next decade – that is around 2005–2010 – there will be a new (technological) driver: billions of devices attached to the Internet.”56 So, ultimately, the communications network will be packet switched, with data transmission accounting for the overwhelming share of traffic, and voice transmission being but one, specialized service.

When in the late 1950s the launching of the first Sputnik alarmed the American high-tech military establishment, ARPA undertook a number of bold initiatives, some of which changed the history of technology and ushered in the Information Age on a grand scale. One of these strategies, developing an idea conceived by Paul Baran at Rand Corporation in 1960–4, was to design a communications system invulnerable to nuclear attack. Based on packet-switching communication technology, the system made the network independent of command and control centers, so that message units would find their own routes along the network, being reassembled in coherent meaning at any point in the network. When, later on, digital technology allowed the packaging of all kind of messages, including sound, images, and data, a network was formed that was able to communicate its nodes without using control centers.

Furthermore, in terms of technological system, one element cannot be imagined without the other: computers are largely determined by chip power, and both the design and the parallel processing of microprocessors depend on computer architecture. Telecommunications is now but one form of processing information; transmission and linkage technologies are at the same time increasingly diversified and integrated into the same network, operated by computers.90 As I analyzed above, the development of the Internet is reversing the relationship between circuit switching and packet switching in communication technologies, so that data transmission becomes the predominant, universal form of communication. And data transmission is based on software instructions of coding and decoding. Technological convergence increasingly extends to growing interdependence between the biological and micro-electronics revolutions, both materially and methodologically. Thus, decisive advances in biological research, such as the identification of human genes or segments of human DNA, can only proceed because of massive computing power.91 Nanotechnology may allow sending tiny microprocessors into the systems of living organisms, including humans.92 On the other hand, the use of biological materials in micro-electronics, although still very far from a generalized application, was already at the experimentation stage in the late 1990s.

The second key technological innovation involved the introduction of standards for packet-switched networks. Previous generations of communication networks had involved circuit switching. In these earlier networks, any communication required the establishment of a dedicated circuit across the parties that wanted to communicate. This circuit would be completely dedicated to the parties involved until they were finished communicating, even if the circuit did not have a lot of traffic at specific points in time. In contrast, packet-switched networks, enabled by digital technology, broke down longer communications into discrete packets of data that could be sent across shared networks. This represented a far more efficient use of network capacity. Although the concept of packet switching as an alternative technology for communicating had emerged in the early 1960s, it was not until the mid-1970s that researchers began to define the TCP/IP standard (Transmission Control Protocol/Internet Protocol) that ultimately provided a foundation for connecting a wide variety of digital networks together.

., where you’ve got thousands of miles of nearly empty interstate highways and railroad lines and huge chunks of rolling stock to carry stuff around. The latter approach works in a place like Shanghai. The same problems of distribution arise in computer networks. As networks get bigger and as the machines that make them up become more equal, the whole approach to moving information around changes from centralized to distributed. The packet-switching system that makes things like the Internet work would be immediately familiar to the Chinese. Instead of requisitioning a hunk of optical fiber between Point A and Point B and slamming the data down it in one big shipment, the packet data network breaks the data down into tiny pieces and sends them out separately, just as a Chinese enterprise might break a large shipment down into small pieces and send each one out on a separate bicycle, knowing that each one might take a different route but that they’d all get there eventually.

Gao, bless him, was the only government official who would talk to me the whole trip—the PRC was still pissed off at the Great Hegemon (as they now call the U.S.) about that incident in the Persian Gulf a few months back when our guys stopped and boarded a Chinese freighter allegedly full of chemical warfare ingredients. They found nothing. Gao calmly rattled off a fairly staggering list of statistics on how rapidly the phone system there is growing—half to three-quarters of a million lines added per year for the foreseeable future. All of their local exchanges are webbed together with fiber, and they’re running fiber down the coast toward Shenzhen. They’re setting up packet-switching networks for their customers who want them—banks, import/export houses, and the like. The cellular and CT2 networks are also growing as rapidly as technology allows. He buys scads of high-bandwidth technology from the West and is actually trying to set up a sort of clearinghouse near Shanghai where Western manufacturers could gain access to the potentially stupendous Chinese market through a single point, instead of having to traffic separately with each regional PTA.

And unlike the ones who built FLAG, they will have the benefit of knowing about the Internet, and perhaps of understanding, at some level, that they are not merely stringing fancy telephone lines but laying down new traces on the circuit board of The Computer. That understanding may lead them to create vast amounts of bandwidth that would blow the minds of the entrenched telecrats and to adopt business models designed around packet-switching instead of the circuits that the telecrats are stuck on. If the network is The Computer, then its motherboard is the crust of Planet Earth. This may be the single biggest drag on the growth of The Computer, because Mother Earth was not designed to be a motherboard. There is too much water and not enough dirt. Water favors a few companies that know how to lay cable and have the ships to do it.

Many phone companies are alread transporting a significant portion of their traffic with IP. Many calls made over telephone compan equipment are already being transported with IP. Packet switched voice over IP systems are in principle as efficient as a synchronous circuit switched systems, but only recently have they had the potential to achieve the same level of reliability as the public switched telephone network or proprietaryPBX equipment. With the invention and implementation of RTP (real time protocol) and SIP (session initiation protocol,) voice over IP has the technological base to obsolete the circuit switched public switched telephone network.

But really, they’re just political entrepreneurs. Big whoop. They are successful with their hands in my pocket. Not a stitch of productivity to be found. Moguls are not Free Radicals. AND THEN THE Internet came along. Oops. Move along—no scarcity here. Cisco routers, and all the other packet-switching network equipment composing the Internet cloud ending up at that broadband router in your basement, send packets of data around to wherever folks want them—no moguls needed. Market entrepreneurs used the chaos of that packet switching to deliver text and pictures to Web sites or phones or even TVs. Then bandwidth got cheap enough to move music around too, shattering the record labels’ control of distribution. And now as bandwidth gets even cheaper and more plentiful, video starts to move around this wild packet network.

By 2008, more than 330 million people had broadband connections, receiving in excess of 100,000 bytes per second.35 To achieve such a staggering 15-fold increase, connection speeds must have doubled roughly every fifteen months, thus outpacing the already phenomenal growth of both processing power and storage capacity. At the same time, monthly connection fees have remained relatively flat, resulting in an equally amazing decrease in communication costs. Moreover, because almost all broadband connections are offered for a flat monthly fee, they create a further economic incentive for users to maximize utilization of the network. Three drivers have facilitated this development. The first is the packet-switched structure of the Internet. Unlike the telephone system, which directly connects two communication parties, information on the Internet travels in small information packets that find the fastest way from sender to recipient independently of each other. This leads to a much better utilization of the available network infrastructure. Second, a huge amount of fiber optic cable ideal for broadband connections has been laid.

From the alien?" The cat, claws extended, delicately picks its way down to her lap and waits to be held and stroked. It never once takes its eyes off him. "Where else?" she asks. "Doctor, I didn't get the Franklin Trust to loan me the wherewithal to build this castle just in return for some legal paperwork, and some, ah, interesting legal waivers from Brussels. We've known for years there's a whole alien packet-switching network out there, and we're just getting spillover from some of their routers. It turns out there's a node not far away from here, in real space. Helium-three, separate jurisdictions, heavy industrialization on Io – there is a purpose to all this activity." Sadeq licks his suddenly dry lips. "You're going to narrowcast a reply?" "No, much better than that: we're going to visit them. Cut the delay cycle down to real-time.

"A network of point-to-point wormholes linking routers, self-replicating communication hubs, in orbit around most of the brown dwarfs of the galaxy. That's what the brochure said, right? That's what we expected. Limited bandwidth, not a lot of use to a mature superintelligence that has converted the free mass of its birth solar system into computronium, but sufficient to allow it to hold conversations with its neighbors. Conversations carried out via a packet-switched network in real time, not limited by the speed of light, but bound together by a common reference frame and the latency between network hops." "That's about the size of it," she agrees from the carved-ruby throne beside him. "Except there's a trade delegation waiting for us. In fact, they're coming aboard already. And I don't buy it – something about the whole setup stinks." Pierre's brow wrinkles.

But in only about ten gigaseconds, the infestation has turned the dead brown dwarf system upside down. They strip-mined the chilly planets to make environments suitable for their own variety of carbon life. They rearranged moons, building massive structures the size of asteroids. They ripped wormhole endpoints free of the routers and turned them into their own crude point-to-point network, learned how to generate new wormholes, then ran their own packet-switched polities over them. Wormhole traffic now supports an ever-expanding mesh of interstellar human commerce, but always in the darkness between the lit stars and the strange, metal-depleted dwarfs with the suspiciously low-entropy radiation. The sheer temerity of the project is mind-boggling: notwithstanding that canned apes are simply not suited to life in the interstellar void, especially in orbit around a brown dwarf whose planets make Pluto seem like a tropical paradise, they've taken over the whole damn system.

They broke up and reconciled repeatedly, and were perpetually on the verge of presenting the ultimate software project, Xanadu, in some formulation, which would have been remembered as the first implementation of the Web, or perhaps even the Internet itself. To be clear, the key technical insight that allowed networking to become decentralized and scale was packet switching, and that insight did not arise from Ted Nelson or the Xanadu project. Instead it arose just a little later than Ted’s earliest work, from the very different world of elite universities, government labs, and military research funding. However, at least the functionality of something like packet switching is foreseen in Ted’s early thinking. Ted published outrageous books. One was a big floppy book composed of montages of nearly indecipherable small print snippets flung in all directions, called Computer Lib/Dream Machines. If you turned it one way and started reading, it was what Che would have been reading in the jungle if he had been a computer nerd.

There is a long and sterile argument to be had about who deserves credit for inventing the internet – government or private industry. Barack Obama is in no doubt that, as he put it in a speech in 2012, ‘The Internet didn’t get invented on its own. Government research created the Internet.’ He was referring to the fact that the decentralised network we know today began life as the Arpanet, a project funded by the Pentagon, and that relied on an idea called packet switching, dreamt up by Paul Baran at the RAND Corporation, whose motive was chiefly to make something that could survive a Soviet first strike and still transmit messages to missile bases to retaliate. Hence the decentralised nature of the network. That’s nonsense, say others. The internet is more than package-switching. It requires computers, communications, all sorts of software and other protocols, many of which the government-funded research projects would have bought from private enterprise.

A handbook for users of the Arpanet at MIT in the 1980s reminded them that ‘sending electronic messages over the ARPAnet for commercial profit or political purposes is both antisocial and illegal’. The internet revolution might have happened ten years earlier if academics had not been dependent on a government network antipathetic to commercial use. Well, then, perhaps we should forget about who was funding the work, and at least give credit to the individuals without whom the internet would never have happened. Paul Baran was first with the notion of packet switching, Vint Cerf invented the TCP/IP protocols that proved crucial to allowing different programs to run on the internet, and Sir Tim Berners Lee developed the worldwide web. Yet there is a problem here, too. Can anybody really think that these things – or their equivalents – would not have come into existence in the 1990s if these undoubtedly brilliant men had never been born? Given all we know about the ubiquitous phenomenon of simultaneous invention, and the inevitability of the next step in innovation once a technology is ripe (see Chapter 7), it is inconceivable that the twentieth century would have ended without a general, open means of connecting computers to each other so that people could see what was on other nodes than their own hard drive.

Given all we know about the ubiquitous phenomenon of simultaneous invention, and the inevitability of the next step in innovation once a technology is ripe (see Chapter 7), it is inconceivable that the twentieth century would have ended without a general, open means of connecting computers to each other so that people could see what was on other nodes than their own hard drive. Indeed, the notion of packet switching – and even the name we now use for it – occurred independently to a Welshman named Donald Davies just a short time after Baran stumbled on it. Vint Cerf shares the credit for TCP/IP with Bob Kahn. So, while we should honour individuals for their contributions, we should not really think that they made something come into existence that would not have otherwise. The names would be different, and some of the procedures too, but an alternative internet would exist today whoever had lived.

Those magical moments when Matthew Broderick managed to get inside that computer system, or when he figured out how to make the free call from the pay phone, or when he was apprehended by the feds—all of us who found ourselves messing around with phones and computers at the time felt like we were living that story because in many cases we were. That thrill—and that fear—is something that never really leaves you. And those of us who experienced it at that relatively early stage of the game were really quite privileged, even though it sure didn’t feel like it at the time. In a big way, the Internet would be the death knell for the kind of hacking most popular in the 1980s. Back then, the most attractive targets were the big packet switched networks like Telenet and Tymnet. These systems allowed you to connect to computers all over the world once you dialed into a local node. Unlike the Internet, it was geared primarily toward businesses and institutions. So if you wanted to play around with it, you pretty much had to break in. We couldn’t get accounts as individuals and we sure couldn’t quell our curiosity. Nor could we effectively explain this to most people.

And apart from all of that, there were massive amounts of new toys to play with as the landscape continued to change. Something as simple as a fax machine or a new consumer service for modem users like PC Pursuit was enough to captivate our attention for huge amounts of time. 94192c04.qxd 6/4/08 3:37 AM Page 121 The Early Days of the Net Hacking on Telenet (February, 1984) Telenet. Or, to be more specific, GTE Telenet. A massive network formed by the people and technology that were used to develop packet switching for the Department of Defense. Telenet was purchased by GTE in 1979 and has been growing in size and revenue ever since. There are quite a few data networks in existence today. Datapac, Autonet, Tymnet, ARPANET, to name some of the better known. A data network is basically a collection of mainframes, specialized minis, and high-speed lines. Through Telenet, you can connect to literally thousands of computers, all over the country, even the world if you know the proper procedures.

Pursuit for People (September, 1985) On August 7, GTE Telenet announced a new service that, if handled properly, will usher in a whole new phase of computer communications. 94192c05.qxd 6/3/08 3:31 PM Page 165 Corporate History The service is called PC Pursuit and it enables people to connect their computers to other computers for $25 a month (plus a start-up fee of $25). In other words, a hobbyist in New York can connect his computer to a bulletin board in California and not have to pay for a long-distance call. The “computer conversation” goes through GTE Telenet, a packet-switching network for computers, previously used exclusively by large corporations. “To access the service,” GTE’s press release explains, “a user calls his PC Pursuit access number and is prompted to enter his home phone number and make a request for a destination phone number in a distant city. If the user’s telephone number is not authorized, the phone call is terminated and a record of the call is generated.

., an email or a web page), and it will try to transfer it in the shortest time possible. While a TCP connection is idle, it doesn’t use any bandwidth.ii If datacenter networks and the internet were circuit-switched networks, it would be possible to establish a guaranteed maximum round-trip time when a circuit was set up. However, they are not: Ethernet and IP are packet-switched protocols, which suf‐ fer from queueing and thus unbounded delays in the network. These protocols do not have the concept of a circuit. Why do datacenter networks and the internet use packet switching? The answer is that they are optimized for bursty traffic. A circuit is good for an audio or video call, which needs to transfer a fairly constant number of bits per second for the duration of the call. On the other hand, requesting a web page, sending an email, or transfer‐ ring a file doesn’t have any particular bandwidth requirement—we just want it to complete as quickly as possible.

If you guess too high, the circuit cannot be set up (because the net‐ work cannot allow a circuit to be created if its bandwidth allocation cannot be guar‐ anteed). Thus, using circuits for bursty data transfers wastes network capacity and makes transfers unnecessarily slow. By contrast, TCP dynamically adapts the rate of data transfer to the available network capacity. There have been some attempts to build hybrid networks that support both circuit switching and packet switching, such as ATM.iii InfiniBand has some similarities [35]: it implements end-to-end flow control at the link layer, which reduces the need for ii. Except perhaps for an occasional keepalive packet, if TCP keepalive is enabled. iii. Asynchronous Transfer Mode (ATM) was a competitor to Ethernet in the 1980s [32], but it didn’t gain much adoption outside of telephone network core switches. It has nothing to do with automatic teller machines (also known as cash machines), despite sharing an acronym.

Data could be scanned for malware and backed up in redundant data farms, some of which would always be disconnected from the network in case of a corrupting system failure. All of these new intranets could use constant scanning technologies to detect and prevent anomalous activity, intrusions, identity theft, malicious software, or unauthorized exporting of data. The intranets could encrypt all data and require that a user prove with two or three reliable methods who he is before he could access the intranet. If the new nets were “packet switched,” as the Internet is now, the user’s authenticated identity could be embedded in each packet. Most important, these networks could constantly monitor for and prevent connectivity to the Internet. A lot of people will hate that idea. Many of the Internet’s earliest advocates strongly believe that information should be free and freely disseminated, and that essential to that freedom is the right to access information anonymously.

Crossing the boundary is an escalatory step that may lead to the war spiraling out of control. DARPA (also seen as ARPA): The Defense Advanced Research Projects Agency is a component of the U.S. Defense Department charged with funding innovative research to meet the needs of the U.S. military. DARPA funded the initial research that created the Internet. In 1969 ARPANET became the first packet-switched network connecting four universities. Deep-Packet Inspection: A procedure that scans the packets of data that make up an e-mail, webpage, or other Internet traffic. Normally only the “header” of a packet is scanned, the top part that gives the to and from information. A deep inspection would scan the digital pattern in the content but would not convert that content into text. The inspection looks only for digital patterns that are identical or highly similar to known malware or hacking tools.

Ultimately, it was Telnet, electronic mail, and ftp, and not NLS, that would generate the demand that led to the dramatic expansion of the computer network. During 1972, Watson also led the charge at ARC to make NLS more useful to the ARPAnet community. ARPA was under some pressure to show that its new network was actually viable, and articles had already appeared in the computer trade press questioning the entire notion of the packet switching that was at its heart. This was a technique for breaking up digital data into small “packets” so that each packet could be routed separately through a computer network and then resent if necessary. It made it possible to route around network nodes that had stopped functioning, making the network more reliable. Roberts had decreed that in October 1972 there would be an event in Washington, D.C., that would show off the network, in much the same fashion that Engelbart had shown off NLS in 1968 in San Francisco.

Throughout late 1975 and 1976, Peddle travelled the country promoting the 6502. His microcontroller became part of an important new technology called the ARPANET (later renamed the Internet). A company named Telenet (later acquired by GTE) created its own commercial network. “GTE had their Telenet packet switching,” recalls Mensch. “Telenet was one of the early fiber providers for the early Internet.” Packet switching required fast processors, and originally the company used costly minicomputers as switches, but then decided to move to something less expensive. “Telenet was a very high performance packet switching for communications systems,” says Mensch. “They tried all the other chips and said the only one that can do it is the 6502.” GTE settled on the 6502 and incorporated the processor in its switches throughout the network, making the 6502 an integral part of the early Internet.

Talk Is Cheap: Switching to Internet Telephones by James E. Gaskin


Debian, packet switching, peer-to-peer, peer-to-peer model, Silicon Valley, Skype, speech recognition, telemarketer

After all, the Post Office isn't held responsible for what individuals mail, and the telephone companies have never been held responsible for what people say to each other over the phone. If the people mail or say something illegal, they may get caught, but the Post Office and telephone company are not considered coconspirators. Bits are bits. And bits in the late 1970s were bits, at least to a study by the Department of Defense. Their own widely publicized report said clearly that a packet switched network, supporting packetized voice traffic, would be cheaper than circuit switched voice, the only technology in place at that time. Bits are bits, and 30 years ago, bits were bits. 1.3.4. Regulatory Issues We can't blame AT&T engineers because they didn't reinvent the telephone on a regular basis; that wasn't their job. The U.S. Government made a deal with AT&T to grant them a monopoly in exchange for building the world's best telephone system.

Or, second, you can capture the first-mover advantage, as Sam Walton, the founder of Wal-Mart, did throughout his career. Even as his retailing rivals were catching up, he was forging ahead with new cost-cutting tactics. Intel’s dominance of the microchip industry, and 3M’s of the diversified technology industry, were based not on protecting their inventions so much as on improving them faster than everyone else. Packet switching was the invention that made the internet possible, yet nobody made any royalties out of it. The way to keep your customers, if you are Michael Dell, Steve Jobs or Bill Gates, is to keep making your own products obsolete. The third way to profit from invention is a patent, a copyright or a trademark. The various mechanisms of intellectual property are eerily echoed in the apparently lawless and highly competitive world of real recipes, recipes devised by French chefs for their restaurants.

What makes the Internet distinct from prior communication networks like the old telegraphs and then telephone networks, however, is that it is packet-switched instead of circuit-switched. Packets are small digital envelopes of data. At the beginning of each packet, essentially the “outside” of the envelope, is the header, which contains details about the network source, destination, and some basic information about the packet contents. By breaking up flows of data into smaller components, each can be delivered in an independent and decentralized fashion, then reassembled at the endpoint. The network routes each packet as it arrives, a dynamic architecture that creates both flexibility and resiliency. Packet-switching was not developed to allow the United States to maintain communications even in the event of a nuclear attack, a common myth.

He was certain that the system it had built would not withstand a nuclear attack. The network was too concentrated; it had no effective redundancy. So he continued to press his idea for a different telecommunications system. He had a different design for telecommunications, and he wanted AT&T to help him build it. This different model was not the Internet, but it was close to the Internet. Baran proposed a kind of packet-switching technology to replace the persistent circuits around which the telephone system was built. Under AT&T's design, when you called someone in Paris, a circuit was opened between you and Paris. In principle, you could trace the line of copper that linked you to Paris; along that line of copper, all your conversation would travel. Baran's idea was fundamentally different. If you digitized a conversation—translating it from waves to bits—and then chopped the resulting stream into packets, these packets could flow independently across a network and create the impression of a real-time connection on the other end.

., 1956). 20 The idea is developed in Kleinrock's dissertation: Leonard Kleinrock, Message Delay in Communication Nets with Storage (1962, unpublished Ph.D. dissertation, Massachusetts Institute of Technology), which was later published in a modified form. See Leonard Kleinrock, Communication Nets: Stochastic Message Flow and Delay (New York: McGraw-Hill, 1964). See also John Naughton, A Brief History of the Future: The Origins of the Internet (London: Weidenfeld & Nicolson, 1999), 92, 118-19 (discussing other earlier contributors to the Internet). 21 Baran attributes to him the discovery of the term. Interview with Paul Baran (“The term 'packet switching' was first used by Donald Davies of the National Physical Laboratory in England, who independently came up with the same general concept in November 1965.”). 22 Baran confirmed this history to me in an interview. “So the first level of objections was about technology—that I didn't understand how the telephone system worked, [and] that what I'm proposing could not possibly work.” Interview with Paul Baran. 23 Naughton, 107.

What maintenance unit? Nibbler hadn’t mentioned any problems with any of the motel’s lines, but Par checked with him. No problems with the telephones. Par felt nervous. In addition to messing around with the phone company’s networks, he had been hacking into a Russian computer network from the computer chalet. The Soviet network was a shiny new toy. It had only been connected to the rest of the world’s global packet-switched network for about a month, which made it particularly attractive virgin territory. Nibbler called in a friend to check the motel’s phones. The friend, a former telephone company technician turned freelancer, came over to look at the equipment. He told Nibbler and Par that something weird was happening in the motel’s phone system. The line voltages were way off. Par realised instantly what was going on.

At least one of them – and often more – had already broken into systems belonging to the European Community in Luxembourg, The Financial Times (owners of the FTSE 100 share index), the British Ministry of Defence, the Foreign Office, NASA, the investment bank SG Warburg in London, the American computer database software manufacturer Oracle, and more machines on the JANET network than they could remember. Pad had also penetrated a classified military network containing a NATO system. They moved through British Telecom’s Packet Switched Stream Network (PSS), which was similar to the Tymnet X.25 network, with absolute ease.2 Gandalf’s motto was, ‘If it moves, hack it’. On 27 June 1991, Pad was sitting in the front room of his parents’ comfortable home in Greater Manchester watching the last remnants of daylight disappear on one of the longest days of the year. He loved summer, loved waking up to streaks of sunlight sneaking through the cracks in his bedroom curtain.

There is no rule that states that someone has to do this, but it remains a protocol of communication that is commonly followed. In the same vein, TCP/IP was developed as a way for any computer to connect and communicate with the ARPANet. More importantly, by using data packet-switching, Cerf and Khan had found a way to eliminate a single point of failure. As there were many computers attached to the network (the ARPANet), a message could be broken into pieces and sent via various channels. If one of the computers was not connected to the network, the message could still be sent via the other computers. This distributed task-management and communication system is the basis of today’s decentralized ledgers. Based on the fundamental principles of packet-switching and a protocol for decentralized communication, other protocols like HTTP, SMTP and VoIP were developed for specific communication purposes. As protocols evolved, they went on to create a digital, decentralized, and distributed environment that was fertile for innovation.

Technology reaches a certain ripeness and the pieces are available and the need is there and the economics look good—it’s going to get invented by somebody.” Paul Baran A few years ago, the unofficial fanclub website of a very popular Spanish band became notorious for reasons beyond their commitment to the band.

The internet was still failing to scale. But by now, it had been failing to scale for more than a decade, very gracefully, very successfully. 11.1.5. VOIP Will Destroy the Internet Then, someone invented Voice Over IP. Some other people decided, why don’t we just replace the entire phone system with the internet? That was a crazy idea. The phone companies then started this massive campaign to inform us of why packet-switched networks could never carry voice. They said, really, the true quality approach to voice was always going to be hierarchical switch networks owned by national monopoly telecom companies because the internet couldn’t possibly scale to carry the world’s phone calls. Those same phone companies (the ones still in business) now route all of their phone calls over the internet. First, they didn’t want the internet on their phone networks.

This is not to say that social, juridical, and political forces do not exert shaping influences that are at least as significant—otherwise we really would have architected our cities around the Segway, and RU-486 would be dispensed over every drugstore counter in the land. But it wouldn't have taken a surplus of imagination, even ahead of the fact, to discern the original Napster in Paul Baran's first paper on packet-switched networks, the Manhattan skyline in the Otis safety elevator patent, or the suburb and the strip mall latent in the heart of the internal combustion engine. Let's draw three emerging technologies from the alphabet soup of new standards and specifications we face at the moment and take a look at what they seem to "want." First, RFID, the tiny radio-frequency transponders that are already doing so much to revolutionize logistics.

GRAPHICAL USER INTERFACE (1968—1974) The use of visual metaphors to represent data on a computer screen, along with the concept of a mouse as pointing device, dates back to a legendary demo by the Stanford professor Douglas Engelbart. Elements of the GUI were also evident in Ivan Sutherland’s 1963 program Sketchpad. The idea was refined and expanded by the Xerox PARC lab in the early 1970s. INTERNET (1970--1975) Assisted by many other computer scientists, the American Vinton Cerf designed and created the original model of the Internet, building on his early research and experiments with packet-switching networks, supported by the U.S. Department of Defense Advanced Research Projects Agency. CT SCAN (1971) Using a grant provided by the British Department of Health and Social Services, British electrical engineer Godfrey Hounsfield conceived and designed the first CT scan (computerized axial tomography), which sent multiple X-ray beams through the human body, providing a near three-dimensional image.

In its plain, unadorned text, Max could follow the exploits of editors Taran King and Knight Lightning, and contributors like Phone Phanatic, Crimson Death, and Sir Hackalot. The first generation to come of age in the home computing era was tasting the power at its fingertips, and Phrack was a jolt of subversive, electric information from a world far beyond Meridian’s sleepy borders. A typical issue was packed with tutorials on packet-switched networks like Telenet and Tymnet, guides to telephone-company computers like COSMOS, and inside looks at large-scale operating systems powering mainframe and mini-computers in air-conditioned equipment rooms around the globe. Phrack also diligently tracked news reports from the frontier battleground between hackers and their opponents in state and federal law enforcement, who were just beginning to meet the challenges posed by recreational hackers.

(BitTorrent is used for a variety of content, but a primary motivation to use it is that it is suitable for distributing large files, such as television shows and feature-length movies.) The internet was, of course, originally conceived during the Cold War to be capable of surviving a nuclear attack. Parts of it can be destroyed without destroying the whole, but that also means that parts can be known without knowing the whole. The core idea is called “packet switching.” A packet is a tiny portion of a file that is passed between nodes on the internet in the way a baton is passed between runners in a relay race. The packet has a destination address. If a particular node fails to acknowledge receipt of a packet, the node trying to pass the packet to it can try again elsewhere. The route is not specified, only the destination. This is how the internet can hypothetically survive an attack.

DARPA was a direct response to the Soviet launch of Sputnik 1 in 1957 and was set up to fund technology research projects that would expand the frontiers of expertise beyond the immediate and specific requirements of the military and its laboratories. It was an extremely flat organization, characterized as 100 scientists and a travel agent, that set out to give major university computer science labs the economic support to conduct basic research that would lead to US technological superiority in computers and networked connectivity. One of its first successful projects was the progenitor of the Internet—ARPANET, the world’s first packet switching network developed in 1962 between four university campuses. Here is the paradox that libertarians just don’t get: the Internet was conceived and paid for by the US government. It was not a product of the free market as we think of it today—the realization of some young entrepreneur’s dreams. It was painstakingly researched and executed by a bunch of academics for whom IPO billions weren’t a reason to work.

And that event included not only the days up until July 23, but also the subsequent repercussions, like the bizarre mass panic, often called the Great Fear, that gripped the provinces over the next week, and the famous legislative session that lasted the entire night of August 4, during which the entire social and political order of the old regime was dismantled.16 The more you want to explain about a black swan event like the storming of the Bastille, in other words, the broader you have to draw the boundaries around what you consider to be the event itself. This is true not only for political events but also for “technological black swans,” like the computer, the Internet, and the laser. For example, it might be true that the Internet was a black swan, but what does that mean? Does it mean that the invention of packet-switched networks was a black swan? Or was the black swan the growth of this original network into something much larger, eventually forming what would at first be called the ARPANET and then this thing called the Internet? Was it solely the development of the physical infrastructure on which other technological innovations, such as the Web and voice-over IP, were built? Or was it that these technologies, in turn, led to new business models and modes of social interaction?

It took only four decades to go from three terminals on a local network to almost seven billion mobile phones, of which two billion are smartphones, on a global network. In the 1960's, mainframes ruled. These were huge expensive machines run like private empires. People were experimenting with simple networks. In 1962, I was born, and someone also invented network packets. These are like envelopes of information that could be sent around different routes to get to their destination. The military began developing packet-switched networks that could survive a lot of damage. Around 1965, people invented mainframe electronic mail; in 1969, the first RFC was written; and in 1971, the @ sign was born. The first Internet was actually built out of smaller networks like Arpanet, which had a whopping 213 hosts in 1981, and Usenet, which had 940 hosts by 1984. The Internet doubled in size every eighteen months. The Internet Protocol (IP) made it possible to route packets between networks (not just inside single networks) and after Big Brother failed to appear in 1984 (except in Apple adverts), the Internet grew into a worldwide research network that reached most places except Africa.

Back then, there were only a few major computing centers on the planet. All those researchers who didn’t happen to work at MIT or Caltech—well, they were just out of luck. Then, in April 1963, a computer scientist named J. C. R. Licklider wrote a memo to his colleagues proposing an “Intergalactic Computer Network”—a network that replaced traditional circuit-switching technology with the then new development of packet switching, allowing any researcher with a terminal and a phone line to connect to one of the computing centers they so desperately needed.4 This was the birth of the Advanced Research Projects Agency Network (ARPANET), the foundational network that has since become today’s Internet. ARPANET became operational in 1975. It was mostly text-based, fairly complicated to navigate, and used primarily by scientists.

If Anubis had the full use of his faculties, he would be more than prepared for anything she could do. But if he was cut off, just a shadow of his full intellect, she might stand a chance. "I'm coming," she said. Her voice echoed from the walls. There was no answering volley of automatic fire; but she felt a sudden prickle throughout her climb-spider's nerves. You are being probed. Mechanism indeterminate and quantum-encrypted. EPR-privileged technology in use. Dreamtime packet-switched scan in use. There is a possibility of viral attack ... Her wisdom base screamed more warnings until she winced it off. "What's going on?" she demanded, firing off a flurry of active radar pulses to map out the dimensions of the killing jar. "I demand to know!" "She demands to know," crooned Anubis. He barked like a dog: feral laughter. Oshi took another step towards the light.

Kleinrock looked over the top of his reading glasses and waved me toward a chair. Then he clicked. And clicked again. Now try, the voice said. He winced. “It says I’m not connected to the Internet. That’s what it says!” Then he laughed so hard his shoulders shook. Kleinrock is the father of the Internet—or rather, a father, as success has many. In 1961, while a graduate student at MIT, he published the first paper on “packet switching,” the idea that data could be transmitted efficiently in small chunks rather than a continuous stream—one of the key notions behind the Internet. The idea was already in the air. A professor at the British National Physical Laboratory named Donald Davies had, unbeknownst to Kleinrock, been independently refining similar concepts, as had Paul Baran, a researcher at the RAND Corporation in Los Angeles.

I’m hoping Vint can give me the big picture on our increasing interconnectedness. After all, he was in at the ground floor of the Internet and now works on the top one. He’s a man with a career-length view on the technology, which for a technology as young as the Net is about the longest view you can have. As a graduate student, Cerf worked under Professor Leonard Kleinrock, who in 1969 oversaw the first computer-to-computer message to be sent using the ‘packet switching’ method that underlies the Internet. Actually, it was two-thirds of a message. Another of Kleinrock’s students, Charley Kline, hoped to send a three-letter message ‘LOG’ to a receiving machine (this being the code for logging on to that computer). The ‘L’ and the ‘O’ worked but the ‘G’ crashed the system. ‘So the first message on the Internet was LO,’ said Professor Kleinrock. ‘Or “Hello,” crash!’

His name was Bram Cohen, and he called his invention BitTorrent. Born in Manhattan, Cohen was a gifted programmer who competed in recreational mathematics tournaments in his spare time. He wore his hair long and his eyebrows thick, his voice came fast and nasal, and he had the hard-geek habit of nervously chuckling at things that weren’t really funny, like the inefficiencies of standard Internet packet switching, or the believability of reported file transfer download speeds. His laugh was startling and staccato, and always felt forced, and when he talked he bounced in his seat and didn’t meet your eyes. These were classic symptoms of Asperger’s syndrome, an autism spectrum disorder that Cohen claimed to have—although, he admitted, this wasn’t a professional diagnosis, merely one he’d assigned to himself.

Today, democracy is a form of open society in which people in authority use the internet for public goods and human security in ways that have been widely reviewed and publicly approved. Democracy occurs when the rules and norms of mass surveillance have been developed openly, and state practices are acknowledged by the government. Information policy has not only come to define what kind of government a country has; the political decision to disconnect information infrastructure now delineates a regime on the edge of collapse. Net watchers report instantly when packet switching through a nation’s digital switches stops and the country “goes dark.” Public protests in an authoritarian regime can be a sign of political instability. A defining feature of political, military, and security crisis is the moment when a ruler orders the mobile-phone company and internet-service providers to shut down. Going dark has become the modern mark of a regime in crisis, and the indicator that a state is close to collapse.

A few weeks after that, two more computers had been added, in Santa Barbara and Salt Lake City. I was familiar with the basic facts of the story and had used the ARPANET story to rebut audiences who wanted to claim the Internet wholly for the 1990s. Being able to meet the man himself was an unexpected honor. Kleinrock, who received the 2007 National Medal of Science in the United States, developed the mathematical background for packet switching, the most elemental network building block of the Internet. His theoretical work on routing network traffic is what today’s World Wide Web operates on. He points out that while it took considerable time to build the hardware and software required for the early networks, the ambition of the people working on the project was always global in scope despite the primitive nature of their early inventions.

She was a collection of trademark affectations: a jacket with built-up shoulders, a monocle, a string tie, nipple tassles, and tattooed cross-hatching on her face that made her look like a woodcut of a Victorian counting-house clerk. Rainer loathed her -- she'd been on the committee to which he'd defended his Philosophy of Networks thesis, and she'd busted his balls so hard that they still ached a decade later when he saw her on the tube. 947 The pundit explained the packet-switching, using trains versus automobiles as a metaphor: "In a circuit uniwerse, every communication gets its own dedicated line, like a train on a track. Ven I vant to talk to you, ve build a circuit -- a train track -- betveen our dewices. No one else can use those tracks, even if ve're not talking. But packet-svitching is like a freevay.

The Egyptians carved obfuscated hieroglyphs into monuments; the Spartans used sticks and wound messages called scytales to exchange military plans; and the Romans’ Caesar ciphers are well documented in school textbooks. Many historians attribute the victory in the Second World War directly to the code breakers at Bletchley Park who deciphered the famous Enigma machine, yet even this monumental technological event, which ended the World War and changed history forever, may pale into insignificance next to changes to come. The packet switching network invented by Donald Davies in 1970 also changed the world forever when the sudden ability of computers to talk to other computers with which they previously had no relationship opened up new possibilities for previously isolated computing power. Although the early telegraph networks almost a century before may have aroused the dream of an electronically connected planet, it was only in the 1970s, 1980s, and 1990s that we started to wire the world together definitively with copper cables and later with fiber-optic technology.

Under these conditions, a print journalist who wants a steady living might feel obliged to heed the advice of major clients and advertisers. 134 ... not the way living organisms do it... Recall how the Internet arose out of concern over how best to defend the United States against foreign foes. Overly rigid central command systems were seen as fatally flawed. New concepts of dispersed responsibility led to packet-switching technology, and eventually the Internetʼs magnificent chaos. 134 Criticism might be viewed as a civilizationʼs equivalent of an immune system.... In fact, mutual criticism in society has the potential of being far more effective in correcting errors than the immune system of a living organism. As John Gilmore points out, “The immune system canʼt improve on the bodyʼs pre-existing design. But criticism can.”

Griffiths, The History of the Internet, Chapter Two: From ARPANET to World Wide Web, (last visited June 1, 2007) (“It is worth remembering, at this stage, that we are still [in the mid-1970s] in a World where we are talking almost exclusively about large mainframe computers (owned only by large corporations, government institutions and universities).”). 32. See Leiner et al., A Brief History of the Internet, supra note 29 (“Internet was based on the idea that there would be multiple independent networks of rather arbitrary design, beginning with the ARPANET as the pioneering packet switching network…. In this approach, the choice of any individual network technology was not dictated by a particular network architecture but rather could be selected freely by a provider and made to interwork with the other networks through a meta-level ‘Internetworking Architecture.’”). 33. Seeid. (“Four ground rules were critical to [the early designs of the Internet]: [First, e]ach distinct network would have to stand on its own and no internal changes could be required to any such network to connect it to the Internet.

He was interested in all forms of technologically augmented human life—what science fiction writers call cyborgs, and what Sigmund Freud meant when he described man as a “prosthetic god.”* The basic story of the Internet’s early development has been told many times; but our specific concern is to understand what was the same and what was different about this network as compared with radio, television, and the telephone system. Licklider and other early Internet founders believed that they were building an information network like none other. Some of its innovations, like packet switching, were obviously radical even in their day. Yet as we have seen time and time again, one generation’s radical innovation is the next generation’s unyielding dinosaur. In this chapter, we begin the pursuit of a central question: Was the Internet truly different, a real revolution? We don’t yet know the answer. But here, at its origins, we can gain the first inklings of what might account for that sense.

The postal service ships high-value goods, whatever they are, either reliably-for destinations in your world, without fear of interception- or fast-for destinations in this world, by FedEx across a continent ruled by horseback." She pushed herself upright with her walking stick. "Put yourself in their shoes. They want nothing to change, because they feel threatened by change-their status is tenuous. A postal network is a packet-switched network, literally so. If world-walkers drift away from it, the bandwidth drops, and thus, its profitability. New ventures divert vital human capital. They're against exploration, because they're scrambling to stay on top of the dung heap." "Sounds like-" Mike could think of a number of people it sounded like, uncomfortably close to home- change the subject. "What about the progressives?" "We want change, simple as that.

In the afterword to my first book, The Net Delusion, I made what I now believe to be one of its main, even if overlooked, points: the physical infrastructure we know as “the Internet” bears very little resemblance to the mythical “Internet”—the one that reportedly brought down the governments of Tunisia and Egypt and is supposedly destroying our brains—that lies at the center of our public debates. The infrastructure and design of this network of networks do play a certain role in sanctioning many of these myths—for example, the idea that “the Internet” is resistant to censorship comes from the unique qualities of its packet-switching communication mechanism—but “the Internet” that is the bane of public debates also contains many other stories and narratives—about innovation, surveillance, capitalism—that have little to do with the infrastructure per se. French philosopher Bruno Latour, writing of Louis Pasteur’s famed scientific accomplishments, distinguished between Pasteur, the actual historical figure, and “Pasteur,” the mythical almighty character who has come to represent the work of other scientists and entire social movements, like the hygienists, who, for their own pragmatic reasons, embraced Pasteur with open arms.

Yet, possibly because they are mostly invisible, we can’t seem to figure out what to call them. None of the commonly used monikers quite capture their importance. One can only wonder how long the oddly durable anachronism “wireless” will stick around. “Cellular” (and the even worse “cellular telephony”) is a technician’s term, mostly confined to use in the United States, which describes the network’s underlying architecture of towers. It’s like calling the Internet “distributed packet-switched computer networking” instead of the “Web.” “Mobile” starts to get at the essence of why people find these technologies so utterly appealing but misses one big aspect of how we use them. Most of the time we aren’t moving, we’re sitting still. There is a more fitting adjective that captures both the technology and what it is doing to us. In the 1990s, as the US military contemplated battlefield communications in the future, it adopted the term “untethered.”

A way therefore had to be found to make telecommunications indestructible in the instance of nuclear war. Telecommunication networks had to become decentralised and distributed, and guided by switching systems able to reroute traffic along whichever connections provided the optimal routes. In around 1965, DARPA commissioned the study of decentralised switching systems, which led to the development of the ARPANET15 packet switching research network, which later grew into the public Internet. ARPANET sent its first email in 1971. Email was thus the Internet’s first ‘killer app’. By the early 1990s, modems made email widely available. Computers began increasingly to connect to the Internet. The ocean was transforming into a new continent where information became a commodity. The invention of the World Wide Web (‘Web’ for short) by English computer scientist Sir Tim Berners-Lee provided a way for computers to share information.

While they were there, a group of other German prisoners sent a message asking to speak to the ‘proper people’. This team had served in the OKW headquarters sigint units and now revealed that, terrified of the rapid Soviet advance, they had buried their equipment under the pavement in front of their headquarters. Called ‘OKW-Chi’, they had successfully broken what was referred to as ‘Russian Fish’. This was an encrypted Soviet military teleprinter that achieved an early version of packet switching, breaking each message into nine different parts and routing it along separate channels, before reassembling it. The Germans had already worked out that their code-breaking triumph would have post-war value, and hoped to sell themselves on as a complete team.4 They were not disappointed. By 23 May they had been encouraged to unearth and set up their equipment, allowing them to resume decrypting Soviet command traffic.

No one is exactly sure when it was first used in relation to technology, but it has been around at least as far back as when network diagrams came into vogue. A network diagram is a graphic representation of the physical or logic layout of a network, such as a telecommunications, routing, or neural. The cloud on network diagrams was used to represent unspecified networks. In the early 1990s, cloud became a term for ATM networks. Asynchronous Transfer Mode is a packet switching protocol that breaks data into cells and provides OSI layer 2, the data link. ATM was the core protocol used on the public switched phone network. As the World Wide Web began in 1991 as a CERN project built on top of the Internet, the cloud began to be used as a term and symbol for the underlying infrastructure. OSI Model The Open Systems Interconnection Reference Model, or OSI Model, is a descriptive abstraction of the layered model of network architecture.

But a series of small power surges could mimic those pulses and activate the motors. The motors might silently rotate, one notch at a time, over the course of days or even months, without the launch crews knowing. And then, when the final notch turned, fifty missiles would suddenly take off. Rubel interview. “I was scared shitless”: The engineer was Paul Baran, later one of the inventors of packet switching.
