Some diagrams of the network are shown below. By 2003 it was no longer possible to show the network in a single drawing.

For diagrams earlier than 1995 one has to scan the transparencies.

Dick and Anna Johnson's recollections of SLAC computing
HEPnet 1985, slide created from from a DEC network management tool called NMCC that shows HEPnet. Just for orientation, FNAL is in the center, SLAC is out to the left, CalTech is below SLAC, with BNL, LBL, and ANL just sort of single points. There's also a number of universities attached, mostly to FNAL. This was just about the time that HEPnet began to act as a network, and not just a bunch of individual network connections directly to the experiment location a university was involved with. The links, of course, were all 9.6 or 4.8kb/s, and the network design was cobbled (vs architected...). But it was one of the earliest really distributed networks (I think Bitnet & Milnet were the only other ones around at that point...). Phil Demar.
