Chinese IP-level network topology measurement and analysis

To build the prospect of Chinese IP-level topology, the traditional destination sampling method was evaluated; three new improved techniques were developed; and Chinese network was measured. With the methodology of complex network, the topology characteristics were extracted and compared. The sizes of autonomous systems (AS) were investigated with the IP2AS technique. The results show that lots of information is missed by the traditional method; the load is reduced to about a half by the new techniques while the completeness is retained; and the size of new discovered Chinese topology is 5 times as many as that discovered by CAIDA's skitter. Compared to skitter's topology, the more complete topology shows more observable dissortativity, weaker clustering, shorter distance and more disequilibrium of node traffic distribution. The heavy-tailed distribution of AS sizes is discovered.
