| 摘 要： | 提出一种基于端到端单播测量的网络拓扑识别方法。在数据测量方面，采用改进的三明治分组探测机制获取往返时延差，进行节点相关性推断。在拓扑推断方面，以树的深度优先序列作为参考，通过比较节点对的相似性，采用迭代与递归相结合的方法反向构建拓扑结构，减少探针发送量。仿真实验结果证明了该拓扑识别方法的有效性。

| Abstract: | This paper presents an identification method of network topology based on end-to-end unicast measurements.For data measurement,it obtains delay difference by improving the sandwich group to infer from the relevant node.For the topology inference,the reference to the tree depth-first node of the relevant sequence comparison,it uses a combination of iterative and recursive methods to build the network topology to reduce the amount of probes sent.Simulation results show that the topological identification method is effective. |
