摘　　要：提出了一种虚拟分布式IPv6路由器级拓扑探测模型——VDPM(Virtual Distributed Probing Model)。VD-PM探测方式既达到了分布式拓扑探测效果,又避免了高昂的部署费用和繁琐的通讯维护工作。本文详细论述了VDPM实现的两个关键问题:虚拟探测源的选取和探测目标点集合的构建。通过对比VDPM方式和纯IPv6单源探测方式以Cernet2为目标网络进行拓扑发现的结果,体现了VDPM作为大规模IPv6路由器级拓扑发现原型系统设计依据的合理性。This paper presents VDPM for IPv6 router-lever topology discovery. VDPM discovers the topology of IPv6 networks in a distributed model and avoids costly fees for deploying and tedious works for communications. This paper also discusses two key issues of VDPM： probing-target sets construction method and virtual probing souce selection method. With the contrasts of the two results which are got from discovery for Cernet-2 with VDPM and native IPv6 access probing model, it can draw the conclusion that VDPM can guide the design of large scale of IPv6 networks topol- ogy discovery system.
