A distributed architecture for Internet router level topology discovering systems

In the past five years, hosts on the Internet have multiplied more than five times, and along with the network´s rapid expansion, more and more attention is paid to the challenging task of studying the topology characteristics of Internet infrastructure. Based on the features of Internet topology discovery and practical experience, we present a three-level distributed architecture for Internet router-level routing topology discovering system. We employ an integrated framework for the deployment of the system. We are examining, from a macroscopic point of view, what architecture is appropriate for this-like system, with an emphasis placed on the flexibility in practical work. The architecture enjoys the advantages of a clear train of thought and high modularization. Experiments show that this architecture has an instructive meaning for the development, deployment, and maintenance of Internet topology discovering system.
