Hey, I'm just trying to pass on my best understanding as I saw it at the time, and in retrospect. If you're not interested, I'm happy to stop. > There were corporate and public access networks long before TCP was set > in stone as a dominant protocol. Sure, there were lots of alternatives (BITNET, HEPNET, SPAN, CSNET, along with commercial systems like TYMNET and TELENET, along with a host of others whose names now escape me). And that's just the US; Europe had an alphabet soup of its own. But _very_ early on (1 Jan 1983), DARPA made all their fundees (which included all the top CS departments across the US) convert to TCP/IP. (NCP was turned off on the ARPANET,and everyone was forced to switch over, or get off the network.) A couple of other things went for TCP/IP too (e.g. NSF's super-computer network). A Federal ad hoc inter-departmental committee called the FRICC moved others (e.g. NASA and DoE) in the direction of TCP/IP, too. That's what created the large user community that eventually drove all the others out of business. (Metcalfe's Law.) Noel
