A functional network presented a conundrum: DARPA did not have charter authority to operate a network. With high demand for networking, and the growth of the network ing equipment companies documented in Chapter 4, there was a clear need for the ARPANET, or something like it, to support commercial needs. Efforts to com mercialize ARPANET technologies were not immediately successful, and networks operated by private companies met some but not all market needs. Elsewhere, research into packet-switching continued along new paths, pro pelled by committed teams of researchers in Europe and the United States. In France, Louis Pouzin led a team of researchers in a project called CYCLADES, with the goal of learning from and improving upon the experience of the ARPANET. And in the United States, Robert Kahn worked with other DARPA-funded researchers to devise methods for passing packets from the land-based ARPANET to the radiobased ALOHAnet. They soon realized that they would need a new protocol for transmitting packets, which led Kahn and his collaborator Vint Cerf to develop the Transmission Control Program (TCP) in 1973. By the mid-1970s, a proliferation of projects and protocols came from Ameri can universities, private companies like Xerox, and European research institutes— all seeking to provide the foundations for network interconnection and support robust commercial and scientific applications.

Press reports routinely compared various solutions in an effort to make sense of the confusion. A key factor in the growing buzz around networking was the unexpected tsunami created by the introduction of the IBM PC in 1981, which continued to inundate the landscape of business computing. Corporate managers had seen the value in desktop computing with the popular ity of spreadsheet applications like VisiCalc for the Apple II, SuperCalc for the Osborne 1 portable computer, and Lotus 1-2-3 for the IBM PC. The success of the IBM PC rapidly accelerated computer purchasing by corporate America. As the bud gets for data processing assumed a larger percentage of total corporate spending, Management Information Systems (MIS) departments became ripe targets for net working products and services—once every corporate desktop became the home of a computer, a flood of new software applications created a demand for shared information at higher communication speeds.

And as with all iconic moments, hundreds of people and decades of effort went into the changes that crystallized in public perceptions as a history-altering spectacle. The 1960s were likewise a pivotal decade for the data communications industry, even if there was little public fanfare to accompany the key developments. Throughout this book we describe market-structures—dynamic relationships between markets and pop ulations of firms that pursue similar product opportunities. During the 1960s, the market-structure for data communications slowly began to emerge, in spite of the dominance of two giant firms AT&T and IBM. The principal obstacle to the emer gence of the data communications market-structure was AT&T’s contesting the attachment of any devices not of its own, as well as the interconnection of other networks, to ‘its’ telephone network. But as we will see in this chapter, the FCC reversed its long-standing support of AT&T in 1968 and allowed independent com panies to sell equipment that connected to the public telephone network. The FCC’s decisions transformed telecommunications—clearing a path for a rush of new businesses forming around new technologies and the growing adoption of business computing. But before we get to the fateful events of 1968, and the extraor dinary events of the next two decades that are the main subject of this book, we need to begin with a brief review of some of the important decisions and events that occurred between the end of World War II and 1968.

Corporations needed to take two steps to leverage the full capability of LANs: first, connect all their computers to LANs, and second, interconnect their LANs into enterprise-wide networks. At the start of 1987, these enterprise networks remained more of a promise than a required capital investment. But it didn’t take long for the new start-ups of internetworking—SynOptics, Retix, Vitalink, Cisco, and Wellfleet—to ship products, and for dozens of other companies to enter the market. By the end of 1988, the third wave of computer communications— internetworking—was under way. As we have seen many times in this history of computer communications, pub lic demonstrations helped to consolidate and publicize existing capabilities while helping to identify the work that remained to be done. Three demonstrations featured the networking and internetworking capabilities of OSI: the National Computer Conference in 1984, the Autofact trade show in 1985, and the Enter prise Networking Event (ENE) in 1988. The alternative to the OSI protocols were those that had been birthed and shepherded by DARPA: TCP/IP. The US federal government had made clear their preference for networks using OSI protocols, not TCP/IP. Nevertheless, a growing band of diehards and vendors eager to market new products continued to offer solutions that leveraged the popularity of TCP/IP.

For over a decade it co-evolved with, and finally eclipsed, the data communications market-structure before the two influenced the emergence, and evolution, of the third market-structure of computer communications: internetworking. By the end of this book, in 1988, total revenues for the three industries combined were over $5 billion. In the early 1970s, a number of pioneering engineers began to apply recent learning in the field of networking to innovate the use of networks for their employ ers’ in-house productivity, or as solutions to meet specific customer needs. But while these pioneers proved the technology could work, it would take until the end of the decade before the commercial success of networks could be validated in the market. By then, the explosion in business computing—mainframes and the increasingly popular minicomputer—had created a compelling need to con nect computers to other computers, peripherals, and terminals throughout the enterprise. Customers began making demands on their vendors for connectivity. This demand was on display in May of 1979 at the Local Area Computer Net working symposium presented by MITRE and the National Bureau of Standards (NBS). The result was a watershed moment for the emerging market, which, when combined with the resurgence of venture capital, provided entrepreneurs with the right mix of opportunity and resources. Just 1 month later, in June, three of the leading networking companies, 3Com, Ungermann-Bass, and Sytek, were founded. Each differentiated to take advantage of what they saw as a unique market oppor tunity. They quickly discovered they did not have the market to themselves, as the existing data communication firms saw the same market signals and responded with products of their own.
