摘　　要：本文在NS2中利用ON/OFF模型产生自相似流,通过检测自相似流的H值,证明该方法是可行的。而在考虑了网络传输机制和网络传输协议后,经过模拟发现网络的自相似性发生了很大变化,同时对网络的丢包率也产生了重大影响。This article use the ON/OFF model produces self-similar flow by NS2, through the H value Of the self-similar flow, Prove that the method is feasible .But just from the source to consider self-similar, not comprehensive enough. Simulation results show that In view of the transmission mechanism of the network, network transmission protocol, Network self-similarity is very different indeed, the resulting flow characteristics of the network also have a major impact.
