****************************************************************************

This talk describes how the TCP protocol
can be modeled in a simulation when traffic is viewed
as fluid flow having piece-wise constant rate functions.
The motivation is to capture essential TCP behavior
in a simulation that runs faster than an
ordinary segment-oriented simulator.  The envisioned
application is generation of realistic background
traffic, when studying _other_ protocols.
Surprisingly, in the continuous formulation we
are still able to capture important TCP features such
as slow-start, congestion-avoidance, time-outs,
lost data, and fast-retransmit.
