基于IP网络的业务流序列生成方法分析

Analysis of sequence generating on IP-Based traffics

随着因特网的迅速增长,对其服务质量(QoS)的需求逐步增加。IP业务流的建模技术是QoS分析的基础。依照因特网的运行经验,业务流呈现自相似性质而不是非平稳泊松过程。本文介绍了自相似业务的特性,对产生自相似业务量的各种方法进行了分析,给出了产生序列的详细步骤,并对这些方法进行了精度和复杂度的对比。

With the explosive growth of Internet ,there is an increasingly demand of quality of service (QoS ).The analysis basis of QoS is the modeling technology of IP traffic flow. According to the experience of Internet operation ,the traffic flow express some selfsimilar feature ,rather than a nonstationary poision process. In this paper, the selfsimilar traffic's characteristics are introduced. Several kinds of methods of sequence generating are analyzed, and a comparing of these methods on precision and complexity is given also. 
