the base pascal/vs implementation on vm used approx. 3090 processor getting 44kbytes/sec thruput. i added rfc 1044 support to the base ... and in some tuning at cray research was getting sustained 1mbyte/sec between a 4341-clone and a cray ... using only modest amount of the 4341-clone cpu (around 25 times the data rate for a small fraction of cpu). misc. past posts mentioning adding rfc 1044 support to http://www.garlic.com/~lynn/subnetwork.html#1044 slight drift ... my rfc index http://www.garlic.com/~lynn/rfcietff.htm other posts on high-speed data transport project http://www.garlic.com/~lynn/subnetwork.html#hsdt we were operating a high-speed backbone ... but were not allowed to actually bid on nsfnet1 (original internet backbone) ... however, we did get an technical audit by NSF that said what we had running was at least five years ahead of all nsfnet1 bid submissions. i was asked to be the red team for nsfnet2 bid ... there were something like 20 people from seven labs around the world that were the blue team (although only the blue team proposal was actually allowed to be submitted). minor past refs: http://www.garlic.com/~lynn/99.html#37a Internet and/or ARPANET? http://www.garlic.com/~lynn/2000d.html#77 Is Al Gore The Father of the Internet? http://www.garlic.com/~lynn/2003c.html#46 diffence between itanium and alpha http://www.garlic.com/~lynn/2004g.html#12 network history http://www.garlic.com/~lynn/2004l.html#1 Xah Lee's Unixism http://www.garlic.com/~lynn/2005d.html#13 Cerf and Kahn receive Turing award http://www.garlic.com/~lynn/2005u.html#53 OSI model and an interview http://www.garlic.com/~lynn/2006e.html#38 The Pankian Metaphor part of old reference from 1988 (although not of the added rfc 1044 support) TITLE IBM TCP/IP FOR VM (TM) RELEASE 1 MODIFICATION LEVEL 2 WITH ADDITIONAL FUNCTION AND NEW NETWORK FILE SYSTEM FEATURE ABSTRACT IBM announces Transmission Control Protocol/Internet Protocol (TCP/IP) for VM (5798-FAL) Release 1 Modification Level 2. Release 1.2 contains functional enhancements and a new optional Network File System (NFS) (1) feature. VM systems with the NFS feature installed may act as a file server for AIX (TM) 2.2, UNIX (2) and other systems with the NFS 3.2 client function installed. Additional functional enhancements in Release 1.2 include: support for 9370 X.25 Communications Subsystem, X Window System (3) client function, the ability to use an SNA network to link two TCP/IP networks, and a remote execution daemon (server). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
