Inet-3.0: Internet Topology Generator
Jared Winick, Sugih Jamin · 2002
Abstract In this report we present version 3.0 of Inet, an Autonomous System (AS) level Internet topologygenerator. Our understanding of the Internet topology is quickly evolving, and thus, our understanding of how synthetic topologies should be generated is changing too. We document our analysis of Inet-2.2, which highlighted two shortcomings in its topologies. Inet-3.0 improves upon Inet-2.2's two main weaknesses by creating topologies with more accurate degree distributions and minimum vertexcovers as compared to Internet topologies. We also examine numerous other metrics to show that Inet3.0 better approximates the actual Internet AS topology than does Inet-2.2. Inet-3.0's topologies stilldo 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 addressedin future work.
