Discovering a Large Scale Internet Topology : Complementary and Contrast View
The Chinese Internet, hosting the world's largest population of Internet users, has largely remained as a black box due to the lack of large-scale measurement infrastructure and various other factors. In this paper, the authors characterize the Chinese Internet AS topology using measurements from both data and control planes. Their analysis emphasizes on the distinct characteristics of the regional network in comparison with the global Internet. To obtain a complete and accurate view, they combine multiple data sources in a complementary manner, including the trace-route conducted on both domestic servers and international Planetlab hosts at the data plane, as well as the Route Views-based BGP routing information at the control plane.
