摘要： 为了解决大型分布式系统由集中管理导致的扩展性和鲁棒性差的问题，利用改进的结构化对等网组织分布式计算资源，将逻辑空间中的节点分为主机节点和资源节点，分别采取相容性Hash和位置保留Hash与对等网逻辑空间匹配，以满足资源信息的范围查询。

Abstract: This paper presents a scalable resource discovery approach by modifying structured P2P network to improve scalability and robustness of the distributed system. The peers are classified to node peers and resource peers. Node peers are computing node in distributed system mapped to logic space by the consistent hash. Resource peers are the abstract peers denoting the node attribute information mapped to logic space by the locality preserving hash. This algorithm supports range query of resource peers.

Key words: P2P network, DHT, resource discovery, consistent Hash, locality preserving Hash
