基于丢包的组播网拓扑发现算法研究

A Study on Loss-based Inference of Multicast Network Topology

由组播网的特点,根据接收节点处丢包的统计,可以推算出组播网络的拓扑结构。文章在组播网络拓扑发现算法BLT的基础上提出了一种基于丢包和跳数的拓扑发现算法HBLT。通过仿真研究表明,HBLT算法比BLT算法有更高的准确性。

According to the characteristic of the multicast network,we can infer the topology of the multicast network.An algorithm HBLT for the inference of multicast network topology is presented in this paper,using the loss distribution and hop information at the receiving nodes,based on the BLT algorithm.The simulation shows HBLT has more correct-ness than BLT does.
