Matt, it is clear you haven't a clue, or half at best. OSI was primarily a "connectionless" protocol, which you didn't know. Its selling point was that it was connectionless. No handshake, which takes time and resources, you just send. It anticipated reliable fast infrastructure. Although at the last minute they brought out a connection oriented protocol for situations where a handshake was essential.
Lord Hall's or Matt's foot?
Matt, it was and even after.
Matt, there was as all the governments and the EU were pushing it. Even in the US NISK were involved.
Nonsense Matt. Read Tenambaum, well the earlier versions. All sorts of clever IP address jiggery pokery was formulated to keep the crock going. The only people who pushed TCP/IP were private companies who had a vested interest in keeping OSI out.
TCP/IP was put together in Snowbird near Salt Lake City. I've been to the hotel where a bunch of students zipped up this inadequate 5 layer stack on backs of envelopes. OSI was deemed to be carrying too much baggage in the headers ay the time. Today with high speed networks this is not a problem. It was stated that it would be fine when infrastructure caught up. You could also have null layers if you liked to speed it up.
Th rapid spread of the Internet and the w.w.w., which had not adopted OSI as it was still being implemeted in various government departments and had not quite reached the rest, killed OSI. Nothing else. It was too late to turn back the TCP/IP protocol. If the www had been two years later it probably would have had an OSI protocol stack.
