| 摘 要： | 设计了一种以环 皮特森图(RP(k))结构为骨干拓扑，以簇为资源节点的文件资源系统环 皮特森簇网格(RP(k)C grid)，讨论了RP(k)C grid系统的消息路由算法. 提出了簇头探察、簇头泛洪和环 皮特森簇(RP(k)C)轮询相结合的probe flooding and scan搜索机制. 对成功跨簇查询的文件在RP(k)C管理节点上建立副本，通过查询登记机制避免簇内泛洪. 实验结果表明，RP(k)C grid有效降低了网络负载和查询延迟，具有良好的可扩展性.

| Abstract: | Overlay network topology and search algorithms have important influence on resource query efficiency. A file resource grid system called ring petersen ( k) cluster grid ( RP( k) C-grid) is designed,it is a hybrid topology overlay network composed of two parts: ring petersen ( k) graph ( RP( k) ) and resource cluster. Message routing algorithms are discussed in detail. Cluster head probe,cluster head flooding and ring petersen ( k) cluster ( RP( k) C) scan mechanism are executed on RP( k) C-grid. Replica is ... |
