Not necessarily so; they had viable if fiarly rudimentary X.25 technology to show. At the end of the seventies one could observe: 1) a large scale production WAN, the ARPAnet 2) experimental or otherwise small scale X.25 technology 3) experimental or otherwise small scale Internet technology 4) papers and intentions about ISO/OSI The ISO people *did* have something going for them; there were X.25 operational networks after all. Now comparisons 1 vs. 2 and 3 vs 4 point out that for *comparable* (ARPAnet vs. "X.25", Internet vs. ISO/OSI) levels of technology you are indeed right when you say that: PADLIPSKY> (Plus, rudimentary awareness of the pace of the international PADLIPSKY> standards process should have indicated that it would take PADLIPSKY> quite some time for OSI to overcome TCP/IP's chronological PADLIPSKY> lead. Say, at least half-a-dozen years as of the late '70s. -- Piercarlo Grandi | ARPA: pcg%uk.ac.aber@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcsun!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@aber.ac.uk
