基于ON／OFF模型的网络流量生成

Generating Network Traffic Based on ON/OFF Model

分析了网络流量的特性，依据网络流量的自相似性，阐述了自相似网络流量生成的方法。以ON／OFF模型为理论依据，设计了生成自相似网络流量的算法，实现了在局域网环境中在线生成满足用户配置要求的网络流量，并对其关键部分代理端的流量生成模块进行了介绍。

This paper analyses the feature of network traffic, and presents the method to generate self-similar network traffic based on the self-similarity of network traffic. ON/OFF model is used to design a generation algorithm. Generating real network traffic according to users＇ requirement is realized on LAN. It contains three kinds of entities： controlling station, agent station and collecting station. Generating traftic module, the critical part, is described in detail.
