  • PART of the PICTURE: the TCP/IP Communications Architecture 1
    PART OF THE PICTURE: The TCP/IP Communications Architecture 1 PART OF THE PICTURE: The TCP/IP Communications Architecture BY WILLIAM STALLINGS The key to the success of distributed applications is that all the terminals and computers in the community “speak” the same language. This is the role of the underlying interconnection software. This software must ensure that all the devices transmit messages in such a way that they can be understood by the other computers and terminals in the community. With the introduction of the Systems Network Architecture (SNA) by IBM in the 1970s, this concept became a reality. However, SNA worked only with IBM equip- ment. Soon other vendors followed with their own proprietary communications architectures to tie together their equipment. Such an approach may be good business for the vendor, but it is bad business for the customer. Happily, that situation has changed radically with the adoption of standards for intercon- nection software. TCP/IP ARCHITECTURE AND OPERATION When communication is desired among computers from different vendors, the software development effort can be a nightmare. Different vendors use different data formats and data exchange protocols. Even within one vendor’s product line, different model computers may communicate in unique ways. As the use of computer communications and computer networking proliferates, a one-at-a-time spe- cial-purpose approach to communications software development is too costly to be acceptable. The only alternative is for computer vendors to adopt and implement a common set of conventions. For this to hap- pen, standards are needed. However, no single standard will suffice.

  • Prologue: the Internet
    Prologue: The Internet (FIXME: How should I handle references in this section?) younger second cousin of mine, Tom, once asked me about how life was before A the Internet. Let us meet again in a few years, and continue that conversation. History Tom: Could you use the Internet when you went to school? Niels: No, I got my first account an a machine with a real Internet connection some year after I entered university, October 24, 1992. Tom: So that was the first time you used email? Niels: Not quite, I got a student account at the cs department some year earlier. The computer system for the students was not directly connected to the Internet, presumably for the protection of the Internet, but one could send and receive email, both locally, to other students and teachers, and to the outside world. Since email was the first big application for the network, it was common with gateways between Internet email, and other systems. I remember having a summer job in the early 1990s at a telecommunications company. We had email, but no direct connectivity to the Internet. It was not possible to connect directly to ftp servers around the world, but some file archives offered an ftp by email service, which we used. Tom: So how did people exchange files before the Internet? Niels: Computer communication was fairly obscure; some people used modems to dial in to bulletin board systems, and hacker groups would exchange data on floppy disks sent via postal mail. It was common that computer magazines and books published program listings, but to try the program, you had to first type it into your computer by hand.

    [3] [Editor's Note: In honor of the 30th Anniversary of TCP/IP we print the following history of the international collaboration that make TCP/IP possible.] The Internet: On its International Origins and Collaborative Vision (A Work In Progress) by Ronda Hauben [email protected] "[T]he effort at developing the Internet Protocols was international from the beginning." Vinton Cerf, "How the Internet Came to Be" ABSTRACT The process of the Internet's development offers an important prototype to understand the creation of a multinational collaborative research project which depends on and fosters communication across the boundaries of diverse administrative structures, political entities, and technical designs. The mythology surrounding the origins of the Internet is that it began in 1969 in the U.S. That is the date marking the origins of the ARPANET (a U.S. packet switching network), but not the birth of the Internet. The origins of the Internet date from 1973. The goal of the researchers creating the Internet was to create a network of networks, a means for networks from diverse countries to inter- communicate. Originally the design was to link up several national but diverse packet switching networks including the ARPANET (U.S.), Cyclades (France), and NPL (Great Britain). When that was not politically feasible, the research project involved Norwegian, British and American research groups, and researchers from other countries, especially France, at various junctures. These research groups did the early development work. The Internet was international from its very beginnings. Preface The following work in progress begins the investigation of the collaboration between researchers from the U.S.
