摘要： 分析网络通信量的传统方法是使用变尺度函数计算Hurst参数,其计算结果不准确,不能正确判断模型拟合度。文章使用主成分分析计算Hurst参数,判断通信量模型的拟合度,分析同一模型不同参数的差别不明显的数据,结果表明该方法新颖而有效。

Abstract: Traditional analysis method for network traffic is the scaled range statistic function(R/S).The results of R/S are not exact and cannot give an accurate judgment of whether the traffic model fitting actual traffic.In this paper the principle component analysis is imported into the network traffic analysis.It is used in computing Hurst parameter and analyzing the data based on different traffic model.It is used in analyzing the data based on the same traffic model with different parameters also.This method is useful and can conveniently give an accurate judgment for complex network traffic trace.
