摘　　要：网格环境中资源的有效管理和发现在网格研究中占有十分重要的地位。文章提出了一种基于语义和P2P技术的新的网格资源发现模型——Semantic-basedPeertoPeerGrid(简称SPTOPGrid)。该模型采用P2P技术进行资源检索,每个peer节点都能提供资源描述和某个知识领域的本体库(ontology);采用publish/subscribe模式进行资源分发;利用语义知识库进行资源的匹配,进行智能化的资源搜索,能够适应网格资源的复杂性、异构性和动态性,具有良好的扩展性。Efficient management and discovery of resources is very important in Grid.This paper presents an efficient Semantic-based Peer-to-Peer （P2P） resource discovery model for Grid （called SPTOPGrid）.In the new model,a P2P network is used to search resources,each peer can provide resource descriptions and an ontology of a certain knowledge domain：a publlsh/subscribe paradigm is used to implement resource dissemination;and the semantic-based match is also used to increase the match accuracy and offers the intelligent search.Our model can adapt to the complexity,heterogeneous and dynamic of the Grid resources,and has a better expansibility.
