Measurement and performance evaluation of NFS traffic in ATM network

摘要

This article has three parts. A t first, we explore traffic chracterization in an ATM local area network and find the traffic presents both long and short range dependence in nature. Secondly, one long range dependent traffic model (fast fractional Gaussian noise) is constructed to explore influence of long-range dependence on the queuing performance of an infinite buffer-size queue. At last, we combine importance sampling scheme and long range dependent traffic models to simulate a finite buffer-size queue. The results show that both LRD and SRD play an important role in the queuing systems. Especially when LRD is strong, the more buffer solution is almost useless to improve the queuing performance. Multiplexing and enough capacity are better solutions for queuing performance.
