A new distributed P2P network architecture basing on active network technology

Gnutella (a pure distributed peer-to-peer network) topology nodes exhibit both typical power-law and small-world property, but the original protocol simply uses flooding algorithm to query peer's information and not uses the property to improve its search efficiency, so there exists poor scalability problem. A new distributed peer-to-peer network model called ADP2PN (Active distributed peer-to-peer network) was proposed by applying active network technology and stratifying the Gnutella network model, and could effectively resolve the problem. In this paper, the architecture and query routing protocol about ADP2PN model were presented and their rationality and validity were analyzed.
