Performance improvement with traffic dispersion in packet networks

摘要

In this paper, by analytical approach and simulation, we study performance improvement with traffic dispersion in packet networks. In the analytical approach, we model a packet network as a queueing model, and we investigate the effect of traffic dispersion on the asymptotic tail distribution of the queue length of packets. In the simulation study, we examine the effect of transport protocols on the performance improvement with traffic dispersion. Numerical results obtained from the analysis show that traffic dispersion can improve the queueing performance of packets. Simulation results exhibit that traffic dispersion can improve the loss performance of UDP sources and that of TCP sources. However, traffic dispersion may improve or degrade the throughput performance of TCP sources.
