[Acpc-l] Vortrag Prof. David NICOL nach Flugzeugschaden

[Alois Ferscha]

Due to technical problems of the aircraft that was 
supposed to fly Prof. Nicol into Vienna last friday
but could not take off, the previously announced talk 
had to be cancelled.

We are happy to announce that the presentation will
be given tomorrow: tuesday, July 18

Again, pls apologize if you receive several copies of
this sendout.

Best regards
Alois Ferscha

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

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.
