中文摘要：

资源发现问题亦即由给定的资源描述找到满足该描述的资源地址。如何快速并且准确地从分布存储的资源中找到所需的资源,是一个挑战性的问题。传统的网格资源发现系统采用注册中心和索引的方式,但这些方式不能满足网格系统规模不断扩大的需求。而对等网络是一种扩展性好的分布式系统,采用已有的P2P技术解决网格环境下的资源发现问题是一种有效的途径。介绍了网格系统中的资源发现、P2P系统的资源发现以及基于P2P的网格资源发现系统,并对它们进行了比较。

英文摘要：

The resource discovery problem is to find the addresses of matching resources by the given description of resources.How to find the needed resources quickly and accurately from the distributed stored resources is a challenge.Traditional grid resource discovery system adopts registry and index,but these methods cannot satisfy the need of increasing scale of grid system.P2P system is a scalable distributed system.It＇s an efficient method to solve the grid resource discovery problem by adopting current P2P technology.This paper introduced resource discovery in grid system,resource discovery in P2P system,grid resource discovery system based on P2P and gave comparisons.
