Internet自治系统级拓扑发现系统的研究与实现

Internet由多个自治系统相互连接而成，AS间的互联结构体现了Internet的宏观结构。研究AS间的连接关系可以辅助分析网络特性。该文研究了Internet AS级拓扑发现，实现了一个Internet AS级拓扑发现系统。该系统分析BGP路由表得到Internet AS级拓扑并直观显示出来。分析了AS级拓扑的度分布属性，分析结果显示生成的拓扑具有幂律分布特性。

Research and Implementation of Internet AS-level Topology Discovery System

Intemet consists of many autonomous systems and the interconnection of the ASes reflect the macrostructure of the Intemet. Research on the interconnection among ASes can help analyze the characteristics of the network. This paper focuses on the discovery of AS-level Intemet topology. It implements an Internet topology discovery system which analyzes BGP tables to get the AS-level topology then display it directly. By analyzing degree distribution properties in the topology, the inherent power-law distribution property of the derived topology can be seen.
