This paper created a SRDM,by modifying structured P2P network to improve scalability and robustness of the large distribution system.The peers in SRDM were classified two kinds,node peers and resource peers.Node peers were computing node in the distribution system for storing resource information and mapped to logic space by the consistent hash.Resource peers were the abstract peers denoting the resource attribute information and the resource peer ID was merged from attribute type ID and attribute value ID.Improved DHT algorithm supported range query of effective resource peers and multiple attri-butes range query.The experiment proves that the new resource discovery approach has higher scalability than the centralization approach.
