RE: the original thirteen NSFNET regionals

  • From: Tony Hain
  • Date: Mon Jun 09 14:39:17 1997

Actually to complete the story, MFEnet preceded HEPnet & SPAN as DEC was
still developing the DECnet protocol at the time. When Sid put together
the proposal for SDSC, it was a clone of the operating and successful
MFE Computer Center (down to the floor plans of the building). The CTSS
operating system for the Cray at that time included the MFEnet protocol.

In that same time frame the MFEnet itself was running out of address
space and worked through a transition to TCP by running MFEnet over IP.

	You actually do not quite have your story right. Sid used MFENET
	(Magnetic Fusion Energy) protocols for the SDSCnet (SDSC
consortium)
	satellite network initially. I was also the networking person at
the
	University of Michigan responsible for the UMichigan-SDSCnet
connection
	(with MFENET protocols) at that time (besides other
responsibilities).
	It did work, and SDSC continued to use it despite the NSFNET
using IP.
	Over time SDSC phased MFENET out and IP in, but besides the
reponsibility
	of the taciturn Teutonic network engineer from Ann Arbor for the
NSFNET,
	I don't think he had much to do with the phaseout of the MFENET
usage
	at SDSC. Sid still claims that he is proud of both his MFENET
decision
	as well as the decision to phase it out, as time moved on.
