摘要：

资源发现的质量与网格系统中资源的组织方式和查询消息的路由方式是密不可分的。随着P2P网络的兴起，许多新的概念和研究方向为网格相关研究提供了思路。该文引入了虚拟组织的相关概念，在此基础上将网格资源进行分层管理，提出了分层C&G体系构架。针对资源查询的处理，给出了3个相关算法：IE算法，ID算法和IR算法。通过实验与传统算法进行了对比，结果表明其性能有了一定的提高。

Abstract: How resources are organized and how messages are routed through the network affect the quality of resource discovery in grid. New ideas are introduced to grid with the development of P2P system. This papers introduces the concept of virtual organization(VO), and divides resources into many VOs according to their types. It presents a layered resource management architecture called C&G, and presents three algorithms for resource management in P2P layer: IE(information exchange), ID(information discovery) and IR(information routing). Compared with traditional algorithms through simulation test, the performance can be improved.

Key words: grid, resource discovery, layer, P2P, Chord, Gossip
