| 摘 要： | 基于CAIDA项目授权的海量数据,结合复杂网络的研究理论和方法,进行了AS级Internet拓扑的CCDF-degree幂律分析和节点时效分析.结果表明,随着AS级Internet拓扑结构的演化,高度值节点部分较为稳定,保持了网络的聚集特性和幂律性,但这部分节点随时间变化逐渐丧失有效连接,同时度值较低的节点的活动比较动荡,Internet的拓扑结构呈缓慢均匀化的趋势.

| Abstract: | Based on the massive data authorized by CAIDA(the cooperative association for Internet data analysis) skitter project,the analyses of CCDF-degree power-law and node aging of the AS-level Internet topology were both made by using the theory and method of complex network.The results showed that with the evolution of the network topology structure the top-degree nodes of the AS-level Internet are relatively stable,thus keeping up the clustering characteristic and power-law of network.However,those nodes will l... |
