Abstract
In discrete­event network simulation, a significant por­
tion of resources and computation are dedicated to the cre­
ation and processing of packet transmission events. For
large­scale network simulations with a large number of
high­speed data flows, the processing of packet events is
the most time consuming aspect of the simulation. In this
work we develop a technique that saves on the processing
of packet events for TCP flows using the well established
results showing that the average behavior of a TCP flow is
predictable given a steady­state path condition. We exploit
this to predict the average behavior of a TCP flow over a fu­
ture period of time where steady­state conditions hold, thus
allowing for a reduction (or elimination) of the processing
