摘要： 分析了网格与P2P资源的特点，提出了一种融合二者资源的UVSP模型，以实现有效的资源表示、发现、访问和协同。根据此模型，为网格加入基于DHT的Bootstrap系统和为P2P系统加入服务化节点。讨论了资源组织体系结构，实现了一个具有BT Tracker功能的系统原型。该模型对网格与P2P系统资源的融合或具有异构拓扑的P2P系统之间的资源共享与协同有参考作用。

Abstract: The characteristic of Grid and P2P systems is analyzed, and a four-layer model called UVSP for grid and P2P resource fusion is presented that has a good character in the resource representation, discovery, access and cooperation. In UVSP model, a Bootstrap based on DHT is added into grid and a peer service is implemented in every P2P node. The resource management architecture is discussed against UVSP. A prototype experiment is realized with BT tracker functionality. The UVSP model is helpful to integrate resources in grid and P2P systems, also available to heterogeneous P2P systems as a reference for resource share and cooperation.

Key words: Grid, P2P, DHT, Web service, Resource management
