With ECGP, peers are grouped into hierarchical clusters according to their topological proximity, and global-peers are selected from regular peers to act as cluster leaders and service providers, achieving the query locality and information interaction between client peers and global peers inside the clusters.

Network topology inference is one of the basic functions of a network management system, and the AS-level topology inference is its focus and difficult point.

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 .

This paper proposes a Core-Tree algorithm that can generate Internet As-level topology graph with two level of the core mesh and the tree-like topology,the distribution of the node s degree,the tree s size and the tree s depth are consistent with the Interne.
