re: http://www.garlic.com/~lynn/2012j.html#98 Gordon Crovitz: Who Really Invented the Internet? majority of the internal network was vm370 ... since MVS/JES2 nodes had to be relegated to mostly boundary nodes ... JES2 was unable to define the complete network and had unpleasant characteristic of discarding traffic if the origin &/or destination node wasn't in its local table. Also JES2 had periodic characteristic of crashing MVS ... when it received traffic that originated at JES2 at didn't release level (in fact, there was large library of VNET NJI drivers to talk to JES2 that specifically reformate traffic originating at other JES2 nodes to try and prevent MVS systems from crashing). also mentioned in this recent post http://www.garlic.com/~lynn/2012j.html#90 Gordon Crovitz: Who Really Invented the Internet? this old post http://www.garlic.com/~lynn/2002k.html#18 Unbelievable references: On p. 13 of The REXX Language by M.F. Cowlishaw, there's a reference to how the development was done. "IBM has an internal network, known as VNET, that links over 1600 mainframe computers in 45 countries." That book is dated 1985. ... but 1600 count would have been when book was written & before actual publication date. this old post http://www.garlic.com/~lynn/2002k.html#26 DEC eNet: was Vnet : Unbelievable. has this statistic BITNET 435 ARPAnet 1155 CSnet 104 (excluding ARPAnet overlap) VNET 1650 EasyNet 4200 UUCP 6000 USENET 1150 (excluding UUCP nodes) ... snip ... also from sometime in 1985 (up from 1000 nodes in 1983). But there are also references by end of 1985 there was 2000 nodes on the internal network ... referenced in this old email http://www.garlic.com/~lynn/2006t.html#email850625 However, the arpanet/internet was rapidly increasing and sometime either late '85 or early '86 passed the internal network in number of network nodes. post containing the 25Jun85 email http://www.garlic.com/~lynn/2006t.html#50 The Future of CPUs: What's After Multi-Core? references 435 BITNET nodes on 18Jan1985, 1155 arpanet nodes 22Jan1985 and by 1988 there were 2691 nodes (BITNET/NETNORTH/EARN). Big boost for arpanet/internet growth was switch-over to internetworking protocol on 1jan1983 (and off the IMP-based arpanet ... approx. only 100 IMPs and 255 hosts on 1jan1983). The other factor in internet exceeding size of internal network ... was the communication group trying to preserve its dumb terminal oriented paradigm ... with the internal network being restricted to mainframe hosts ... while the internet nodes were starting to include a growing number of workstation and PC nodes. there were numerous efforts by communication group to protect their dumb terminal paradigm and install base ... also discussed http://www.garlic.com/~lynn/2012j.html#90 Gordon Crovitz: Who Really Invented the Internet? -- 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
