【摘要】 在如今大规模的网络环境中,为了解决传统资源发现机制不能很好的适应网络状态、异构等特点的问题,提出了一种基于Mesh结构的资源发现模型。该模型结合了集中式和对等网模型的优点,在中央节点之外,还引入了超级节点的概念,将整个资源搜索过程划分为本地搜索和全局搜索,从而减少了查询时的时间开销。通过理论分析和实验结果,该模型能有效的提高网格环境下的整体性能。更多还原

【Abstract】 In order to improve resource discovery efficiency in current dynamic and heterogeneous grid environment,a mesh-based resource discovery framework was discussed,which combined the advantages of centralized and Peer-to-Peer frameworks.The model introduced the concept of super-node and divided querying process into local search and global search besides a center-node.Thus the overhead of querying was cut down.Theoretical analysis and experi- ment show that this model performs scalable and efficient in grid environment.更多还原
