You're right, the TCP peak was 1.48Gbps from the show floor in Dallas to a
storage cluster at Berkeley Laboratory.  Single applications using multiple

convention center to DARPA's HSCC pop node.

This beat last years (SC'99) 1.2 Gbps rate Microsoft achieved running TTCP
on a single PC with 2 Gbit Ethernet cards (Redmond to Portland).

Peak rate alone is a meaningless measure of performance. The TCP session may
have reached peak for a small fraction of the session duration and the rest of
the time, the link may have been severely under-utilized.
A meaningful performance measure here is average or percentile link utilization
over the tcp session duration.
