| 摘 要： | 针对目前数据网格环境中已有的副本定位方法和P2P中的数据定位方法提出了一种基于小世界模型和对等代理的副本定位模型。利用小世界特性和物理网络的远近划分各个虚拟组织（VO），在VO内部采用一个代理用来存储该域内的全局副本定位信息，在VO间各个代理是对等的关系，采用对等代理机制进行副本定位，并对其高效性、可靠性及可扩展性进行了评价分析。

| Abstract: | A replica locating method based on Small-world Theory and peer agent was proposed in allusion to current replica locating method in Data Grid environment and P2P data location method. A virtual organization was divided by using the Smallworld character and network. In the inner domain global replica locating information was storaged by an agent. While among the inner domain all agents were peer to peer and peer agent mechanism was used, This replica location mechanism was estimated on high-efficiency, reliability and decentralization. |
