Research and realization on large scale IPv6 backbone network topology discovery
大规模IPv6骨干网拓扑发现研究与实现

In view of the fact that there always exist problems in the present large scale discovery of IPv6 backbone network topology such as low efficiency and short of coverage rate, this paper brought forward a network topology discovery scheme on choosing the probing target by self-learning, which was based on ICMPv6. By virtue of IPv6 source routing mechanism, also solved cross-link problem and the multiple access router problem both of which often exist in the present topology discovery. Finally, it was proved through the experiment on the topology discovery for the IPv6 backbone network around the world and the national backbone network that the scheme presented largely enhances the discovery efficiency while also ensuring a high coverage rate at the same time.
