一种基于小波的网络流量发生器设计

Design of A Self-similar Network Traffic Generator Based on Wavelet

网络流量发生器在网络性能分析和协议实现中具有重要的作用。文章基于多分形小波模型,设计了一种自相似网络流量发生器。其中对随机数的生成、序列的截断、自相似序列的生成以及自相似流量的生成等主要设计部分进行了论述。与常用的基于分形布朗运动的模型的流量发生器相比,该发生器生成的流量具有更准确的自相似流量特性。

Network traffic generator plays an important role in analyzing the per formance of network and implementing network protocols. A self-similar network traffic generator based on multi-fractal wavelet model is designed. The main de signing components are discussed which include random number generation, serials truncation, self-similar serials generation and traffic generation. Compared t o the one based on fractional Brownian motion model, this traffic generator can give more exactly self-similar traffic.
