Abstract: Network management becomes more and more important for today’s Internet, and the Internet’s topology plays a key role in the Internet’s fault avoidance, configuration management and performance improvement. However, accurately obtaining the Internet’s topology has become a difficult problem for a long time. This paper proposes a novel multi-source topology mapping methodology based TraceNET, and applies this approach for mapping the topologies of the campus network of USTC and CERNET. The measurement results suggest that this method solves the router IP alias resolution and the subnet discovery problems very efficiently, and accurately obtains the network topologies in terms of routers and subnets, therefore providing valuable topological information on the Internet for network management and study.

Key words: TraceNET, topology measurement, Internet Protocol（IP） alias resolution
