Relationship to BITNET?

Article states that VNET was developed by IBM, but its no clear to me if it was in fact based on BITNET or not, and what the extent of inter-breeing between the two was. linas 18:48, 31 July 2006 (UTC)[reply]

There was lots of cross-breeding, but IBM's VNET network pre-dated BITNET. See Melinda Varian's magnum opus, VM and the Community. RossPatterson (talk) 01:27, 31 October 2008 (UTC)[reply]

The VNET is the IBM internal corporate network which was based on SNA not RSCS as Bitnet was and existed oh maybe a decade before Bitnet. Gateways existed between the VNET (private, highly corporate and fairly academic Bitnet, both directly and indirectly using the ARPAnet. It developed as a bit of frustration on Ira Fuchs' part with the slowness of IBM getting a networking product out. --enm, 2:20, 2 Nov 2007 (UTC) —Preceding unsigned comment added by 70.90.161.236 (talk)

The first VNET nodes were non-SNA, and used what in those days was known as "bisync networking" or "bisync NJE". In fact BITNET was built using the same technology as that earlier VNET network, and (nostly) stayed that way. RossPatterson (talk) 01:30, 31 October 2008 (UTC)[reply]

VNET was first deployed as a private host to host network among CP/67 and VM/370 mainframes begining before 1975. It was based on RSCS, a virtual machine based communications program. RSCS used synchronous data link protocols, not SNA/SDLC. It supported file to file transfer among virtual machine users. The first several nodes included Scientific Centers and Poughkeepsie, New York lab sites. I was personally involved in these early deployments. Tag314159 (talk) 14:37, 17 November 2007 (UTC)[reply]
