iNet拓扑生成

Inet是密歇根大学于1999~2002年间开发的一个AS 级拓扑产生器,最新发布的是3.0版本。其特点是利用route-views.oregon-ix.net上从1997年11月到2002年2月间的大量 BGP数据来确定拓扑度量的值，可信性很高。Inet采用PLGR算法与优先附着实现幂律,重视连通性(最小节点覆盖)，并针对最大团尺寸和聚类系数做了 优化。Inet使用简便，只需在命令行输入拓扑图节点总数即可。

Inet, currently at version 3.0, is an Autonomous System (AS) level Internet topology generator. Our understanding of the Internet topology is quickly evolving, and thus, our understanding of how synthetic topologies should be generated is changing too. Inet-3.0 improves upon Inet-2.2's two main weaknesses by creating topologies with more accurate degree distributions and minimum vertex covers as compared to Internet topologies. Inet-3.0 also better approximates the actual Internet AS topology than does Inet-2.2. Inet-3.0's topologies still do not well represent the Internet in terms of maximum clique size and clustering coefficient. These related problems stress a need for a better understanding of Internet connectivity and will be addressed in our future work.
