摘要
针对网络仿真的需要,在对实际网络流量进行拟合的基础上,设计了基于Gamma分布和小波方法的流量仿真模型。对拟合效果的评估显示,该模型较好地刻画了网络流量的自相似特征,为网络流量仿真提供了一种有效的方法。
According to requirement of network simulation,a Gamma distribution and wavelet based network traffic simulating model is presented based on real backbone network traffic fitting.Evaluation shows that the model illustrates the self-similar property of real backbone network traffic ,and it provides an effective method for network traffic simulation.
