介绍Internet的复杂网络特征,采用RouteViews项目公布的数据分析了近十年来Internet拓扑特征的演化情况,总结出Internet发展的三个阶段.针对网络拓扑演化过程中不同特征参数之间可能存在的关联性问题,采用相关性计算的方法对网络特征参数进行了聚类分析,并使用主分量分析法指出在Internet演化过程中起主要作用的参数集合.
This paper introduces the complex network characteristics of the Internet and analyzes the evolution of Internet topology characteristics in the past ten years by using the data published by RouteViews project and summarizes the three stages of Internet development.Aiming at the possible correlation between different characteristic parameters in the process of network topology evolution Problem, we use the method of correlation calculation to cluster the network characteristic parameters, and use principal component analysis to point out the parameter set that plays a major role in the evolution of the Internet.
