TCP and IP bake offs

The so-called TCP and IP bake offs were a series of early interoperability tests of initial implementations of the TCP and IP protocols.

Implementation demonstration

Four prototype implementations of TCP/IP were tested for mutual interoperability at an 'implementation demonstration' held as part of a internet meeting held at ARPA (the testing, in the afternoon, was actually performed at DCEC) on 4 December, 1978. This was likely the very earliest attempt to get different TCP implementations to connect to each other. They were:

• Terminal Interface Unit for the LSI-11 from SRI in MACRO-11
• UNIX Sixth Edition for the PDP-11 from BBN in C
• OS/MVT for the IBM 360 from UCLA
• Multics for the Heneywell 68/80 from the LCS

ISI bake off

6 prototype implementations of TCP/IP were tested at a 'TCP Bake Off' held at ISI on 27-28 January, 1979. They were the four above, and:

• UNIX Sixth Edition from BBN in Macro-11 (itself a port of the TIU implementation, above)
• TENEX for the PDP-10 from BBN
