TCP/IP versus OSI - ISO reference model

1988 National Institute for Standard Technology (NIST) mandated ISO-complient protocols for all computers sold to the US Government.

TCP/IP still dominated so edict was rescinded in September, 1994.

UCB UNIX distribution in 1980’s included the TCP/IP protocol suite.

It works.

It is available.
