网络拓扑结构

This method combined the traceroute result with the topology information obtained by tomography to construct a final topology using minimum similarity cluster algorithm and merging and constructing anonymous routers algorithm.the simulation on ns2 shows that this method not only be able to infer the network topology which contains uncooperative routers, but also enormously reduce the number of probes.

Then a BGPEOpt(BGP Egress Optimization Algorithm) algorithm is proposed to reduce the execution time of the typical algorithm by leveraging the .characteristics of cut link in the topology graph to reduce the frequency of recomputing traffic demand. Further more, mediate results are used in the iterative process to reduce the time of computing the IGP shortest distances from a source node to other nodes. Experimental results indicate that the running time of BGPEOpt reduced 7%~30% with the similar link utilization comparing to that of typical algorithms.
