Abstract: The study of self-organizing network is a hotspot in the next generation network (NGN) research domain. P2P as one of the four technologies will shape the Intemet'sfuture. I3y building P2P overlay network on top of Internet's physical topology layer based on P2P computing mode, we can effectively build a full-decentralized Internet based self- organizing network routing model-Hierarchical Aggregation Self-organizing Network (HASH). I}he target and architec- lure of HASN were described in this paper, as well as a detailed description of a P2P decentralized naming, route discov- Bring and updating algorithm-HASH_ Scale. Simulation results testify the performance of HASH.

Key words: Peer-to-Peer network, Self-organizing network, Structured overlay network, Hierarchical routing table
