Abstract:

Aiming at the shortcomings of the existing methods for IPv6 network topology discovery,a distance-based integration algorithm is proposed for IPv6 campus network. In the algorithm,by using the subnet information of OSPF ( Open Shortest Path First) routing protocol,the results of the Traceroute6-based and OSPF-based topology discovery methods are integrated with the shortest distance between nodes as the metrics. Then,they are adjusted according to subnet prefixes,interfaces,etc. Finally,the proposed algorithm is tested in the real network environment and compared with the hop counts-based integration algorithm. The results show that the proposed algorithm can not only integrate the topology results rapidly and effectively but also improve the integrity and accuracy of the topology information.

Key words: IPv6, campus network, topology discovery, integration algorithm, Traceroute6, open shortest path first
