摘要
研究表明网络流量具有自相似特性,而自相似网络流量的生成是网络性能分析的一个关键环节,为此设计了一种生成网络背景流量的方法。在VC++环境中对该方法进行了仿真,验证了其有效性。进一步将该方法应用于卫星网络仿真,对卫星网络端到端的延迟进行了初步分析,结果表明网络流量的突发特性影响着卫星网络的性能,这是在进行卫星网络路由优化与流量分配时需要考虑的因素。
It is generally accepted that network traffic could be characterized by self-similarity.It is important to genera-te network traffic according to this principle for network performance analysis.A scheme for network background traffic generation was given,and it was validated by a program implemented in VC＋＋.Furthermore,this procedure was used to simulate satellite network and help to analyze end to end delay.It suggests that bursty traffic has influence on satellite network performance.This factor should be carried to satellite network routing optimization and traffic allocation.
