摘　　要：通过研究Internet自治层的拓扑结构,以及在Internet小世界现象内的偏好连接、节点和链接的随机或优先消亡、节点间非线性优先连接、新节点所带来的外部链接及网络内新增的内部链接等诸多因素,提出了基于小世界现象的Internet拓朴模型。通过仿真实验与统计数据的对比表明,ITMSW模型能够很好的描述Internet自治层无标度、小世界现象等诸多特性。This paper researches the topology of Internet＇ s autonomous layer, Internet＇ s preferential attachment,random or preferential death of nodes and links ,nonlinear preferential attachment between nodes ,new nodes addition with external links and new internal links addition between existing networks in small world phenomenon.This paper proposes an Internet topology model based on small world phenomenon model.Compared with simulation experiments and the statistical data of Internet,the fact states ITMSW model enables to well describe Internet topology features which include autonomous layer scale-free,small world phenomenon and so on.
