the assumptions you described in earlier mail. (Also, more bandwidth seems
to be available to "TCP/IP" than appears to be available from ATM...)
I believe that the number is for TCP/IP carrying capacity _without_ ATM.
One could remove the ATM overhead, but then one has a point-to-point
link, rather than a link over which data from many sources can be
multiplexed.
Rather, that leaves us with the excellent (very desirable) option of a
link where data from many sources are multiplexed by TCP/IP....
I do not see what ATM buys in this situation.
