| 摘 要： | 提出基于小波包分析的网络流量随机模拟算法,通过应用小波包变换将实际测量的网络流量分解为2"个不同分量(n为分解的层数),再将这些分解长度相等的每个分量进行等分,进行这些等分分量的随机组合形成2"个分量,再重构,最后对模拟合成的网络流量进行自相似特性的分析.实验结果表明,用该方法模拟的网络流量具有较好的自相似性.

| Abstract: | A simulation algorithm of network traffic based on wavelet packet analysis is presented,the network traffic collected from real network is decomposed into different 2 variable based on wavelet packet(n is the decomposed layer).The recomposed 2 variable is randomly obtained from lots of the same length variable,then are decomposed from the original 2 variable.The recomposed 2 variable is analyzed by self similarity.Statistical analysis shows that the network traffic generated by this way possesses high degre... |
