非协作方式下IPv6接入网络拓扑发现

Non-cooperative Topology Discovery Method for IPv6 Access Networks

本文致力于提高非协作方式下IPv6接入网络拓扑发现的覆盖率,首先建立了描述IPv6接入网络的前缀聚合树模型(PATM,Prefix Aggregation Tree Model),然后提出了基于PATM模型的网络拓扑发现方法。最后给出了对华东某高校IPv6校园网的拓扑发现测试结果。通过对测试数据进行的分析和对比,验证了基于PATM模型的拓扑发现方法的有效性。

This paper is mainly applied to some methodologies on improving the coverage of non-cooperative topology discovery for IPv6 access networks. This paper proposed the PATM （Prefix Aggregation Tree Model） to depict the IPv6 access networks, and it proposed the topology discovery methodology on the base of the PATM. In the end, the paper proposed the results of topology discovery for an IPv6 access network of a university in the east of china and proved the efficiency of topology discovery methodology with the analysis of the test results.
