摘　　要：提出了一种针对映射关系查询的预缓存策略:在负责存储节点映射关系的接入交换路由器中设置缓存,将缓存算法应用于通信建立后映射关系的查询过程中.仿真结果表明,预缓存策略和接入路由器缓存策略能有效提高映射关系查询命中率和通信效率.A pre-caching strategy was presentsed to solve the query of mapping relationships and set a cache in the access switch router which stores the nodes＇ mapping relationships.Then the cache algorithm is applied to the query process of the mapping relationships after the communication is established.Finally,there is an analysis about the pre-caching strategy and the access switching router＇s cache strategy.The result showed that the use of the pre-caching strategy and the access switching router＇s cache strategy can improve the hit rate about mapping relationships and improve communication efficiency.
