Aggregation technique for networks with power law traffic and application to accelerated simulation

The authors present an accelerated simulation technique for packetised networks, and examine the accuracy and speedup obtained when it is used in studies of power law traffic, including cases where the sojourn times have been truncated to imitate real network operation. The aggregation concept has also been applied to an end-to-end path, where both the number of end-to-end nodes and the number of traffic sources at a node are aggregated. It is shown that very accurate results are obtained in combination with significant simulation acceleration.
