摘　　要：介绍了一种灵活高效的分布式网络流量生成方法；通过加入权重因子，利用反馈机制不断对产生的网络流量进行调整直至流量大小误差符合用户设定需求；结合ON／OFF模型，采用分布式结构产生了流量速率可调节的具有自相似特性的网络流量。通过该方法产生的网络流量大小精确可控，且具有自相似性，能更好地反映出真实网络流量的特性。This paper proposes a new method of generating flexible and high-speed network traffic. Via importing the power gene, using the reactive mechanism, continually adjusts the network traffic speed until the error matches the user＇ s initialization. Combining ON/OFF model, adopting distributed framework, generates self-similarity network traffic and the speed of which is adjustable. Through this way, the speed of generating network traffic is precise and controllable, and takes on self-similarity characteristic. Thus it can reflect the characteristic of the real network traffic better.
