中文摘要：
设计了一种以RP（k）为骨干拓扑结构、以Cluster为资源节点簇的文件资源网格RP（k）C-Grid。提出了查询登记机制,以提高簇头节点资源发现能力。以及基于目录广告的资源感知模型,使得查询不用或少量泛洪即可找到所需资源的信息。实验证明RP（k）C-Grid具有良好的可扩展性和资源发现效率。
英文摘要：
A file sharing system called RP（ k）C-Grid is designed. It is a hybrid topology overlay network composed of two parts： a RP（k） backbone and resource cluster. A query register mechanism is proposed to enhance the cluster head nodes ability of resource discovery. A resource awareness model based on directory advertisement is introduced to improve resource awareness abihty of the cluster head nodes without flooding. Experimental study reveals that the RP（ k）C-Grid has good efficiency in scalability and resource discovery.
