用层叠模型分析和估计网络业务量

Analyzing and Estimating Network Traffic with Cascades Model

该文给出了用小波变换形式的层叠模型分析业务量的完整步骤,并通过实验证实这个分析方法的适用性.文中特别指出,在进行分析时不宜使用单位时间内分组到达数和分组到达间隔时间序列来对应模型中的随机过程,而应该用它们的累加序列,因而可更全面地分析网络业务量.

The cascades model proposed recently from self-similar and multifractal model stem can be used to analyze network traffic comprehensively. This paper, therefore, puts forward an integrated process using cascades model in pattern of wavelet transform to analyze network traffic and further justifies the feasibility of the method. Meanwhile, it emphasizes specifically that, the cumulant sequences of the sequences denoting the number of packet arrivals in unit time and that of inter-arrival time between packets, instead of either of both,should be considered as the stochastic process of the model.
