<div class="moz-cite-prefix">This does not really answer my original
question, I consider asking Van directly, but I see that TCP
resembles swabian "Kässpätzle". (cheesy noodles.) Everyone has his
own recipe, there is not "that one standard" and the real clues in
preparing them aren't written in any textbook.<br>

<div dir="ltr">Hi Bob,
<div><br>
</div>
<div>That sounds about right. IIRC, there were a lot of TCP
implementations in various stages of progress, as well as in
various stages of protocol genealogy - 2.5, 3, 4, and many
could communicate with themselves or selected others prior to
January 1979. Jon's "bakeoff" on the Saturday preceding the
January 1979 TCP Meeting at ISI was the first time a
methodical test was done to evaluate the NxN interoperability
of a diverse collection of implementations. </div>
<div><br>
</div>
<div>I remember that you were one of the six implementations in
that test session. We each had been given an office at ISI
for the day and kept at it until everyone could establish a
connection with everyone else and pass data.</div>
<div><br>
</div>
<div>There were a lot of issues resolved that day, mostly having
to do with ambiguities in the then-current spec we had all
been coding to meet. As we all finally agreed (or our code
agreed) on all the details, Jon tweaked the spec to reflect
what the collected software was now doing. So I've always
thought that those six implementations were the first TCP4
implementations to successfully interoperate. Yours was one
of them.</div>
<div><br>
</div>
<div>There was a lot of pressure at the time to get the spec of
TCP4 nailed down and published, and that test session was part
of the process. Subsequently that TCP4 spec became an RFC,
and a DoD Standard, and The Internet started to grow, and the
rest is history....</div>
<div><br>
</div>
<div>I wonder if Dave Clark ever forgave Bill Plummer for
crashing the Multics TCP by innocently asking Dave to
temporarily disable his checksumming code....and then sending
a kamikaze packet from Tenex.</div>

I wrote a TCP back in the 1979 timeframe - the first one
for a Unix<br>
system, running on a PDP-11/40. It first implemented
TCP version<br>
2.5, and later evolved to version 4. It was a very
basic<br>
implementation, no "slow start" or any other such
niceties that were<br>
created as the Internet grew.<br>
<br>
I have been trying to recall where my TCP/IP for UCLA's IBM
360/91 ran in this horse race. The best I can tell from IEN
70 and IEN 77 is that my TCP-4 version made it between Dec
1978 and Jan 1979, although I think I had an initial TP-2.5
version talkng to itself in mid 1978.<span class="HOEnZb"><br>
