摘　　要：网格被认为是下一代网络,而网格资源发现机制是实现网格上层应用的基础设施。目前,已经有了网格的一些实现系统,并提出对应资源发现机制。论文首先介绍了现有的资源发现机制并指出了它们的不足。然后从资源描述、资源组织等方面进行分析提出把网格建立成大资源库的构想,并结合P2P领域的研究成果,采用分层结构化方法实现了基于三层重叠拓扑的网格大资源库,同时提出了相应的资源发现机制。其中基于系统实现提出了改进的CAN协议、可扩展的域入口、可迁移的用户注册策略、可伸缩的管理服务机制等方法和手段来提高网格系统性能和资源发现效能。Grid is considered as next generation network,however resource discovery mechanism in grid is basic establishment of implementing other top applications.Now,there are some implementation systems of grid and corresponding resource discovery mechanism.In this paper,we first presented the existing resource discovery mechanisms and pointed out their deficiency.Then,through analyzing description and organizing of resource,we put forward an idea of building grid into a big resource warehouse.And combining research production in P2P,we adopted the layered structural method to realize the idea that has three layers of overlap topology structure.At the same time,we put forward corresponding resource discovery mechanism.For improving the performance of system and the efficiency of resource discovery,we also applied some new methods in the system,such as improved CAN protocol,scalable entry of domain,movable mechanism of user register and extendable mechanism of management service.
