摘　　要：网格中资源发现机制是把资源提供者和资源请求者联系起来的重要环节。在分析分层分布式分群监控体系结构和现有资源发现机制的基础上,提出将集中式目录服务、资源路由表和移动代理三种机制相结合的网格资源发现机制。实验验证该机制在小范围内查找具有性能高效的特点,而在大范围内查找减少了资源发现代理的分发数量,降低了系统消息的负载,进而降低了网络资源的占用。Resource discovery mechanism is a key tache connecting the provider and requestor of resources. According to the analyzing and researching on the current resource discovery mechanisms and the hierarchical distributed and cluster monitoring architecture, the thesis presents a resource discovery mechanism combined the centralized directory service, resource routing table and mobile agent. The experiment shows that the mechanism has a higher discovering performance in a small scope, moreover decreases the number of resource discovery agents dispatched in a large scope, reduces the load of system and network.
