Inet Topology Generator

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.
