Just to avert any confusion... I see (Communications Week, June 7, 1993, pg 1) that the code name for IBM's soon to be announced ATM (asynchronous transfer mode) switch happens (?) to be "Clipper." It's apparently based on "IBM's experimental Planet switch, a 6 gigabit per second switch that handles both variable and fixed length packets" and is in test at Rogers Communications in Toronto. (Just in case you hear communications types using the term "Clipper" in a different sense from the one usually seen on this list.) -- Dr. Tom Keenan, I.S.P. Associate Dean, R&D, Faculty of Cont. Ed.
