【摘要】 提出了网格环境下教育资源发现机制模型,将P2P技术引入网格资源发现中以实现分布式资源查找,提高其可扩晨性,针对教育资源的特点,进行了基于类别的虚拟社区划分,对资源请求的查找可限定在所属虚拟社区内进行,从而可缩小搜索空间,提高资源的发现速度。更多还原

【Abstract】 An educational resource discovery mechanism in grid environment is studied , in which the p2p technology is introduced to grid resource discovery so as to realize the decentralized resource query and improve the scalability. According to the character of educational resource, virtual communities based on classification are organized and queries for resource are performed only in given community, by which the search space can be reduced and the efficiency of resource discovery can be improved.更多还原
