... and remember the sna organization non-concurred with announcing appn/awp164
(until after the announcement letter was carefully rewritten so that
there was no relationship between appn and sna).
for more trivia ... email from day appn was announced ... and for some total
trivia ... at this time ... both the author of appn/awp164 and i (directly)
reported to the same executive.

Lynn,
I just got back from San Francisco and I'm having a little trouble
keeping up with all the network traffic .... John sends almost as many
emails as you..
Your est. of 60000 terminals for Bell South is about right as I recall
and the US West number is between 50 and 60K I'd guess.
I also found a Washington Systems Center Tech Bulletin on SNA Networks
of Small Systems (GG66-0216) which is interesting reading on LEN and
points out the design point for the prototype (and the S/36 APPN which
they announced today Advanced Peer to Peer Networking...nice name) for
small networks. It seems to me that the extensions required to handle
a large network of arbitrary topology and high speed data are non
trivial at best. The directory search algorithm and storage required
to support it appear to be very large indeed. Also, once a route has
been selected, it is frozen so that session recovery in the event of a
node failure on the route would (I have to assume) result in the loss
of the session...not the case in XXXXXX (except at the host boundary
which could be changed to recover even that session without a session
outage). As you know, XXXXXX can have major processor failures within
the NTC, NHC or NXC and continue without session interruption.
