we were out making customer executive presentation on 3-tier architecture, involving ethernet, routers, mainframes, etc. ... when we were taking sharp barbs in the back from the token-ring and SAA forces (communication group strongly fighting off distributed computing and client/server, trying to preserve their dumb terminal paradigm and install base). some past posts http://www.garlic.com/~lynn/subnetwork.html#3tier Part of the T/R forces critism involved comparing 16mbit t/r with what it claimed was ethernet ... but they only way they could make those numbers come out was if they used pre-product 3mbit ethernet before listen-before-transmit. I would make facetious references that obviously somewhere in the bowels of Armonk (or Raleigh) that they have time-machine to justify comparing 1990 token-ring technology with 1980 ethernet. as an aside, my wife had also included 3-tier architecture in response to large, very secure, gov network campus request ... and took a lot of heat & FUD. as I've periodically mentioned, in the late 80s a senior disk engineer got a talked scheduled at the world-wide, internal, annual communication group conference supposedly on 3174 performance ... but opened the talk with the statement that the communication group was going to be responsible for the demise of the disk division. As referenced the communication group was fightting off distributed computing and client/server and the disk division was seeing data fleeing the datacenter to more distributed computing friendly platforms with drop in disk sales. The disk division had come up with a number of solutions but were constantly vetoed by the communication group (with its corporate strategic ownership of everything that crossed the datacenter walls). http://www.garlic.com/~lynn/subnetwork.htmL#terminal In the early 80s, we were working with the director of NSF and suppose to get $20M to interconnect the NSF supercomputer centers. Then congress cuts the budget, some other things happened and finally an RFP was release (in part based on what we already had running). Internal politics prevent us from bidding and the NSF director tries to help by writing the company a letter (with support of other agencies), but that just makes the internal politics worse (as did comments that what we already had running was at least 5yrs ahead of all RFP responses. As regional networks connect into the centers, it evolves into the NSFNET backbone, precursor to the modern internet. some old email http://www.garlic.com/~lynn/lhwemail.html#nsfnet and posts http://www.garlic.com/~lynn/subnetwork.html#nsfnet somebody collected the email going around the communication group with lots of misinformation and FUD ... and forwarded it to us ... heavily snipped and REDACTED to protect the guilty: http://www.garlic.com/~lynn/2006w.html#email870109 and other SNA/VTAM misinformation http://www.garlic.com/~lynn/2006x.html#email870302 http://www.garlic.com/~lynn/2011.html#email870306 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
