Visualization of Asian AS topology evolution

In this paper, we propose a method to infer regional-level AS topologies and compare the Asian AS topologies in 2004 and 2010. With the Internet being globalized, the global traffic has become increasingly common between two countries. Analysis of AS topology is helpful to understand the macroscopic Internet structure and evolution. But AS topology shows a relationship of AS organizations, so only using existing method is difficult to observe the regional Internet structure changes. Our method focuses attention on the place of BGP routers, infer the places of AS boundaries and mapped geographical information and AS topology data. In result, we show the growth of each Asian countries in Asia. And our method has enabled to observe the regional Internet structures.
