Abstract: Internet topology graph is a powerful tool to develop and utilize Internet on a large scale. The Internet As level topology graph portrays Internet characteristic on the autonomous system level and has the widespread application on many domains at present. This paper proposes a Complete-Waxman-Tree(CWT) hiberarchy algorithm that can generate Internet As-level topology graph with three levels, which are consistent with the Internet very well in the distribution of the node’s degree, the tree’s size and the tree’s depth.
