Utah graphics hidden line removal Crocker recounts that these four sites were selected because they were "existing ARPA computer science research contractors. This made it natural that UCLA received one of the first nodes, as it would be important to measure the network's activity from early on - one of the first two or three sites had to be the measurement site in order for the statistics to be based on correct data for analysis purposes and UCLA accordingly came to be the Network Measurement Center NMC [ 26 ].

The Network Working Group Once the initial sites were chosen, representatives from each site gathered together to talk about how to solve the technical problem of getting the hosts to communicate with each other.

The Completion Report Draft tells us about this beginning: Shapiro called a meeting in the summer of which was attended by programmers from several of the first hosts to be connected to the network. Individuals who were present have said that it was clear from the meeting at that time, no one had even any clear notions of what the fundamental host-to-host issues might be [ 27 ].

The first meeting took place several months before the first IMP was configured. The group had to begin with a blank slate. In Crocker's recollections of the important developments produced by the NWG which were provided as the introduction to RFC, the reader is reminded that the thinking involved was ground-breaking and thus exciting.

Crocker remembers that the first meeting was chaired by Elmer Shapiro of SRI, who initiated the conversation with a list of questions [ 28 ]. These attendees, most of them graduate students, were the programmers described in the Completion Report Draft.


According to Crocker, this was a seminal meeting. The attendees could only be theoretical, as none of the lowest levels of communication had been developed yet.

They needed a transport layer or low-level communications platform to build upon. It was important to meet before this date, as the NWG "imagined all sorts of possibilities" [ 29 ]. Only once they started thinking together could this working group actually develop anything.

These fresh thoughts from fresh minds helped to incubate new ideas.

The Completion Report Draft properly acknowledges what this early group helped accomplish. A concrete decision made at the first meeting was to continue holding meetings similar to the first one. This set the precedent of holding exchange meetings at each of their sites.

Crocker, describing the problems facing these networking pioneers, writes: With no specific service definition in place for what the IMPs were providing to the hosts, there wasn't any clear idea of what work the hosts had to do.

Only later did we articulate the notion of building a layered set of protocols with general transport services on the bottom and multiple application-specific protocols on the top.


More precisely, we understood quite early that we wanted quite a bit of generality, but we didn't have a clear idea how to achieve it. We struggled between a grand design and getting something working quickly [ 31 ]. These languages were more advanced than what was needed and could not be implemented at the time.

The basic purpose was to form an on-the-fly description that would tell the receiving end how to understand the information that would be sent.

The discussion at this first set of meetings was extremely abstract as neither ARPA nor the universities had conceived of an official charter. However, the lack of a specific charter allowed the group to think broadly and openly. This information gave the group some definite starting points to build from.

As all the parties had different priorities, the meeting was a difficult one.


BBN was interested in the lowest level of making a reliable connection. The programmers from the host sites were interested in getting the hosts to communicate with each other either via various higher-level programs. Even when the crew from BBN did not turn out to be the "experts from the East," members of the NWG still expected that "a professional crew would show up eventually to take over the problems we were dealing with.

The participants decided it was time to start recording their meetings in a consistent fashion. Crocker writes about their formation: I remember having great fear that we would offend whomever the official protocol designers were, and I spent a sleepless night composing humble words for our notes.

The basic ground rules were that anyone could say anything and that nothing was official.The precursor to the Internet was jumpstarted in the early days of computing history, in with the U.S.
