基于Traceroute的IPv6自治域间网络拓扑发现技术研究

Research on IPv6 AS-Level Topology Discovery Technology Based on Traceroute

互联网由IPv4向IPv6过渡,获取针对IPv6的自治域间拓扑非常必要。文章介绍了基于Traceroute进行IPv6自治域间网络拓扑发现的基本原理,重点阐述了针对IPv6海量地址空间的探测列表构建方法,对拓扑发现过程中出现的MOAS(多源AS)现象成因进行了分析,详细描述了拓扑发现算法。该算法对于IPv6自治域间拓扑发现有重要参考意义。

Now the Internet is migrating from IPv4 to IPv6, so it＇s essential to get the IPv6 AS-level topology. This paper discusses the basic principle based on traceroute to discover IPv6 AS-level topology, presents a method of constructing IPv6 probing address list aiming at IPv6 enormous address space, analyses the reason for MOAS （Multi Origin AS） phenomenon during topology discovery process, and gives a particular description of the algorithm. This algorithm has important reference value for IPv6 AS-level Topology discovery.
