网络流量自相似性影响因素的研究

网络流量特征是分析和研究网络性能、规划网络建设的基础。由于自相似模型能够更加真实地描述网络传输的特性，通过生成自相似性的流量进行仿真研究。提出将业务源流量自相似性与网络传输的TCP协议相结合进行研究的方法，探讨影响自相似流量的因素，分析网络行为随参数变化的情况。仿真结果表明业务源流量的自相似与网络状态无关，而网络传输的TCP协议自适应改变网络状态，从而间接改变网络流量的自相似性，但并不能消除业务源流量的自相似性。

Research of Network Traffic Self-similarity Effect

The nature of network traffic is the basis of network design and performance analysis.Because of network traffic having self-similarity nature,the simulation research for generating network traffic with self-similarity has been done.Meanwhile we propose to combine self-similarity of source traffic with TCP protocol,study the effect of traffic self-similarity,and analyze the behavior of network traffic.The simulation results show that self-similarity of source traffic will be independent of network state,whi...
