- HEPnet 1985, slide created 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.
