I just have to make some comments. We, at UC Irvine , as part of the DCS project that I was PI of , had a 2.5 megabit token ring working in the mid 70's . This ring later became the IBM Token Ring after some interesting parts had been removed. Bob Metcalfe has said that he did the Ethernet cause we did the token ring. For the additional record, the DCS was a fully distributed system operating over a LAN offering transparent process migration, load sharing, contract resource control (auctioning) and utilizing the new minicomputers that were just appearing. Besides being the first I know of that actually did distributed computing, it ran in metal rather than in conference proceedings and was fault tolerant and smoothly adapted to failures.

or that Robert Metcalfe was the father of local area networking (!!! his clumsy two-megabit, thick-wire Ethernet was hopelessly impractical, and never would have been widely commercially successful)
Ethernet I was three-megabit. Datapoint's ARCNet was 2.5-megabit. It was originally coax, but later implementations of its transceiver worked over a single CAT-3 twisted pair (aka phone wire). ARCNet was *sweet*. I tried to get Clarkson University to let me wire one dormitory using these twisted-pair ARCNet boards, but Clarkson's "We Shall Take no Risk Before Its time" IT management saw no applications for dormitory networking in 1988. Couldn't even get permission to do a technology demo of wiring one room. -- -russ nelson http://russnelson.com | Okay, enough is enough!
