摘要: DoubleTree算法是一种重要的IP级网络拓扑发现方法,极大减少了探测冗余,但该方法会产生大量的网络通信量,增加了网络负担。本文在DoubleTree算法的基础上,通过对全局停止集存放结构的改进,实现了DoubleTree++算法。实验证明,该方法在达到95%的网络覆盖度的同时,减少了50%探测冗余,并且降低了探测源点间的网络通信量。

Abstract: The DoubleTree algorithm is one of the important IP level topology discovery methods. It can reduce probe redundancy dramatically; however, it also brings about a great deal of network traffic, promoting the network burden. In this paper, a DoubleTree++ algorithm based on DoubleTree, is designed and implemented via improving the storage structure of the global stop set.The experiment shows that DoubleTree++ can reduce 50% probe redundancy and decrease the network traffic among probe sources, while covering 95% network nodes and links.

Key words: network topology;probe redundancy;DoubleTree;communication traffic
