Multiple Autonomous systems (ASes) of the network are usually consisted of many routers such as inter-router and intra-router connection each other. In order to detect the network routers connection relationship, many researchers at home or abroad use various methods such as active end-to-end links detection or observing SNMP MIBs to understand the links’ connection relationship among the routers in network’ ASes. In this paper, by using the link prediction algorithm based on the similarity, we tried to predict the links’ connection relationship and got the possible network topology structure among the network’ ASes when the actual connection link don’t be completely detected. Through the experiments, the prediction results can be seen that the similarity algorithm index of ACT, SRW, and SimRank based on the random walk can also achieve better prediction accuracy above 0.95, which prove the similarity index especially the random walk algorithm can realize the higher link prediction accuracy to the network’ ASes under the conditions of missing some known connection link, etc.
