The description of Licklider’s introduction to computers is based on personal interviews with Wes Clark and Jack Ruina, and on Licklider’s interview with the Charles Babbage Institute, as well as the Barber Associates report. Chapter Two The description of Paul Baran’s work on distributed communications is based on personal interviews with Baran, as well as various interviews conducted by the Babbage Institute. The description of Donald Davies’s early work on packet-switching is based on interviews and correspondence with Donald Davies, and on Martin Campbell-Kelly’s articles and interviews. Arthur Norberg and Judy O’Neill’s awesome report, “A History of the Information Processing Techniques Office of the Defense Advanced Research Projects Agency” also guided us through biographical material and through the early years of IPTO. The report served as the basis for their book Transforming Computer Technology: Information Processing for the Pentagon, 1962–1986 (Johns Hopkins University Press, 1996).

Evolution in science, as in nature—normally a gradual sequence of changes—occasionally makes a revolutionary leap breaking with the course of development. New ideas emerge simultaneously but independently. And so they did when the time was ripe for inventing a new way of transmitting information. In the early 1960s, before Larry Roberts had even set to work creating a new computer network, two other researchers, Paul Baran and Donald Davies—completely unknown to each other and working continents apart toward different goals—arrived at virtually the same revolutionary idea for a new kind of communications network. The realization of their concepts came to be known as packet-switching. Paul Baran was a good-humored immigrant from Eastern Europe. He was born in 1926, in what was then Poland. His parents sought refuge in the United States two years later, following a lengthy wait for immigration papers.

By the following spring, confident that his ideas were sound, he gave a public lecture in London describing the notion of sending short blocks of data—which he called “packets”—through a digital store-and-forward network. As the meeting was breaking up, a man from the audience approached Davies and said that he was from the Ministry of Defence. He told Davies about some remarkably similar work that had been circulated in the American defense community by a man named Paul Baran. Davies had never heard of Baran or his RAND studies. Donald Davies was the son of working-class parents. His father, a clerk at a coal mine in Wales, died the year after Donald and his twin sister were born. Their mother moved her young family to Portsmouth, a British naval port, where she went to work as a counter clerk in the post office. Donald experimented with radio at a young age and took an early interest in physics. He was not yet fourteen the day his mother brought home a book, something an engineer had left behind at the post office, all about telephony.

Since every major computer manufacturer was following a proprietary strategy designed to prevent connections between dissimilar systems, the Arpanet represented a government-funded project that sought to compensate for this evident market failure.14 The most distinctive attribute of the Arpanet was its reliance on packet-switching, a new method of transmitting data across telephone lines that had been invented independently in the mid-1960s by Paul Baran at RAND Corporation and Donald Davies at Britain’s National Physical Laboratory (NPL). Where traditional circuit-switched telephone networks required a direct, dedicated connection between users, packet-switched networks broke data into discrete blocks, which Davies dubbed “packets,” that contained basic information about their places of origin and destination. Packets could be transmitted indirectly and asynchronously throughout nodes in the network before eventually arriving at their destination, where they would be reassembled into their original form.

It was a resounding success – even if utterly baffling to the ten AT&T executives who attended and reportedly declined ARPA’s offer to operate the Arpanet or even purchase it outright.24 The meeting in Washington did more than host the Arpanet’s coming-out party; it also provided an ideal opportunity to invigorate international cooperation. 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 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.

All the bits of information in every computer at CERN, and on the planet, would be available to me and to anyone else. There would be a single global information space.44 In 1984, when Berners-Lee returned to CERN and discovered the Internet, he also returned to his larger vision of a single global information space. By this time, he’d discovered the work of Vannevar Bush and Ted Nelson and become familiar with what he called “the advances” of technology giants like Donald Davies, Paul Baran, Bob Kahn, and Vint Cerf. “I happened to come along with time, and the right interest and inclination, after hypertext and the Internet had come of age,” Berners-Lee modestly acknowledged. “The task left to me was to marry them together.”45 The fruit of that marriage was the World Wide Web, the information management system so integral to the Internet that many people think that the Web actually is the Internet.

McCulloch’s ideas about the brain as a self-governing network helped Baran to arrive at concrete pragmatic solutions to the overarching military orders of his employer. The Internet, in this sense at least, traces its intellectual sources back to cold war cybernetics. Baran’s network innovations do not arrive without serious institutional and international complication. Although technically on target, Baran’s ideas were not influential until after a foreigner—an Englishman named Donald Davies, with the UK Post backing him—independently discovered and articulated packet switching. Only then did Baran’s superiors in the U.S. military-industrial complex start paying attention to his ideas. In fact, between 1960 and 1966, AT&T repeatedly declined or delayed his proposals to develop digital communication networks. As one AT&T official told him, the near nationwide monopoly on analog telephony networks was not about to go into competition with itself.

The most impressive of these is the “great firewall of China,” which permits elites and technical experts an escape hatch from the Chinese walled-garden version of the global Internet. International communication networks also helped to jumpstart and also consign to limbo local computer network projects. This account highlights three case studies: first, Anatoly Kitov’s discovery of Norbert Wiener’s Cybernetics in a secret military library set into motion an internal transition in Soviet scientific discourse; second, Donald Davies and the British Telecom industry prompted the U.S. government to revisit Paul Baran’s RAND research on distributed packet-switching networks; and third, news of the ARPANET going online in 1969 prompted the Politburo to revisit the decade-old OGAS proposal in 1970. In each case, international communication networks (even when they were closed or secret) initially prompted internal institutions to revisit concurrent innovations closer to home.

As long as they flowed fast enough, and the computers at both ends were quick, the conversation encoded in this packet form would seem just like a conversation along a single virtual wire across the ocean. Baran was probably not the first person to come up with this idea—MIT loyalists insist that that was Leonard Kleinrock.20 And he was also not the only person working on the idea in the early 1960s. Independently, in England, Donald Davies was developing something very similar.21 But whether the first, or the only, doesn't really matter for our purposes here. What is important is that Baran outlined a telecommunications system fundamentally different from the dominant design, and that different telecommunications system would have effected a radically different evolution of telecommunications. BARAN pushed to get AT&T to help build this alternative design.

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.

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. Thus if a telegram was sent from, say, New York to San Francisco, the message might pass through intermediate switching centers in Chicago and Los Angeles before arriving in San Francisco.

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. Fortunately, just as Roberts was confronting this problem, the first minicomputers had started to enter the market and the solution came to him in a eureka moment in a taxicab ride: the interface message processor (IMP).

Because the system was digital, not analog, individual messages could be easily broken up into smaller pieces and then reassembled at the end of the system with perfect fidelity. This, too, accentuated the resilience of Baran’s architecture; even the messages themselves were mini-networks of data, with each partial message finding its own way across the broader network. Baran called his approach “distributed adaptive message block switching.” 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.”

One of the first such exercises in economics was MIT economist Joshua Angrist’s work examining the effect of military service on men’s subsequent earning ability in the labor market. To avoid the problem that men who choose to join the army may be inherently different from those who do not, Angrist used the Vietnam War–era draft lottery, which had created random recruitment. He found that men who had served in the early 1970s ended up earning about 15 percent less a decade later than men who had never served.15 Columbia University economists Donald Davis and David Weinstein used the US bombing of Japanese cities during the Second World War to test two models of city growth. One model was based on scale economies (decline in production costs as urban density increased), and the other was based on locational advantages (such as access to a natural seaport). Even though the bombing was obviously not random, it created a natural way to test whether cities that had been badly destroyed would remain depressed or bounce back to their original position.

A third possibility is that it had formed elsewhere in the solar system and was later captured by the Earth’s gravity. Theoretical calculations show that capture into orbit is highly unlikely: if a Moon-size body were to come near the Earth, it’s a lot more likely to have either hit the Earth directly or received a gravity kick that set it fying off into space. In the early 1970s, two sets of theorists—one consisting of Alistair Cameron and William Ward at Harvard and the other of William Hartmann and Donald Davis of the Planetary Science Institute in Tucson— independently suggested that the Moon formed from the debris of a giant impact that the Earth had with a Mars-size roaming planet. But it took nearly a decade before planetary scientists widely accepted that catastrophic impacts had been common in the early solar system. In computer simulations of the event, the im-pactor is destroyed, and a plume of rock, magma, and vapor is boosted into Earth orbit.

Unfortunately, we have only rudimentary information on the location of unexploded bombs, untriggered land mines, and 228 N O TES the use of the herbicide/defoliant Agent Orange. But we can reasonably assume that the number of still-active explosives in any given location is very closely related to the quantity of bombs that were dropped there during the war. 4.

And as he sat down afterward, he had reason to feel satis- fied: this was something genuinely new in the world, a way to organize commu- nications that was radically different from anything that had gone before. Except that shortly thereafter, an Englishman named Roger Scantlebury got up to give a paper on a system being developed by Donald Davies's telecommu- nications research group at the National Physical Laboratory (NPL) in Tedding- ton, outside London-and proceeded to describe essentially the same idea: packets, IMPs, distributed control, the works. What the. . . ? The story, as Scantlebury would explain it to the disconcerted Roberts later that day, was both ironic and sad. The irony was that Donald Davies had got- ten his original inspiration when he was hosting a conference on time-sharing back in late 1965 and fell into an impromptu discussion about networking with J. C. R. Licklider and Roberts himself. Almost immediately after that, Davies had been struck by the notion that a store-and-forward system with very short message segments would be perfect.

Rechtin's basic strategy was for the agency to keep a low profile, to build allies among the services, and to give them technology they could use. Operational technology. That wasn't a category that included much on IPTO's agenda-not Project MAC, not Engelbart's center, and certainly not the network. With the technical design for the network still in draft form at that point, the entire effort could eas- ily have been stopped right there, leaving Larry Roberts just as thoroughly stymied by the bureaucracy as Donald Davies and Paul Baran had been before him. And yet somehow it didn't happen. ARPA's computing program continued to lead its charmed life, rather like a person sleepwalking through a battlefield without getting a scratch. One reason was DDR&E Johnny Foster, who resisted any and all attempts to focus ARPA's efforts purely on Vietnam. The DoD had THE INTERGALACTIC NETWORK 279 other concerns during this period, after all, starting with the Soviets' rapidly ex- panding nuclear capability.

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. Baran’s work, begun in 1960 at the request of the US Air Force, was explicitly aimed at designing a network that could survive a nuclear attack. Davies, working in an academic setting, merely wanted to improve England’s communications system. By the mid-1960s—by which time Kleinrock was at UCLA, on his way toward tenure—their ideas were circulating among the small global community of computer scientists, hashed out at conferences and on office chalkboards.

The drug and music countercultures and the early technological innovators informed and inspired each other – and were often the very same people. The acronymic utopias enabled by internet technologies such as TCP/IP aren’t so different from those offered by LSD: equality, connectedness, awareness of life as a sum greater than its parts. 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.

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.

Justquotes.com is a great example of a site that serves both as a useful pathfinder to specific (namely investing) Invisible Web resources, but that saves the time of the researcher by pre-configuring what amounts to custom searches with the stock symbol of interest to the searcher. To paraphrase the popular television commercial, “No search engine gonna do all that.” Case 8 – The Invisible Web Fails to Deliver! Donald Davis feels very familiar and comfortable with the visible and Invisible Web. He has read numerous articles on the subject and knows his way around many of the better Invisible Web pathfinders. In fact, he recently accessed some key economic statistics via the Invisible Web. Donald is trying to track down several newspaper articles for a business proposal he is writing and feels confident that his knowledge of the Invisible Web will come in very handy.

ARPANET, the Internet’s predecessor, was rolled out in the early 1970s. So legend has it. The real story is more prosaic. There were indeed real concerns about the survivability of military communications networks. But RAND was just one of several research groups that were broadly rethinking communications networks at the time—parallel efforts on distributed communications were being led by Lawrence Roberts at MIT and Donald Davies and Roger Scantlebury at the United Kingdom’s National Physical Laboratory. Each of the three efforts remained unaware of each other until a 1967 conference organized by the Association for Computing Machinery in Gatlinburg, Tennessee, where Roberts met Scantlebury, who by then had learned of Baran’s earlier work.17 And ARPANET wasn’t a military command network for America’s nuclear arsenal, or any arsenal for that matter.

“In a very short period of time—within the past decade, the research effort devoted to these ends has developed from analyses of how a mechanical mouse might find his way out of a maze, to suggestions of the design of an all-electronic world-wide communications system,” he wrote in 1964.54 Baran christened his technique “adaptive message block switching,” abbreviated to “packet switching” in 1966 by Donald Davies, working independently at the U.K. National Physical Laboratory. The first order of business was to take all forms of communicable information—text, data, graphics, voice—and break it up into short strings of bits of uniform length. To the network, all forms of communication would look the same. Error-free transmission of complex messages would be facilitated, for the same reason that the reproduction of complex organisms can best be achieved in a noisy environment through the collective reproduction of large numbers of smaller component parts.

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. The true origin of the internet does not lie in brilliant individuals, nor in private companies, nor in government funding.
