摘　　要：为了实现对海量多源数据资源的统一管理和资源共享,满足分布数据存储环境下对数据的统一管理和高效检索要求;利用LDAP(lightweight directory access protocol)轻量级目录服务访问协议进行设计并实现了分布式资源目录系统结构,并在此基础上针对服务器间查询速率低的问题提出了应用最短路径算法提高查询速率的方法。实验结果表明,利用LDAP协议实现了分布式资源目录的存储及管理,应用最短路径算法能够显著提高分布式资源目录的查询效率。To realize unified data management and resource sharing of the massive resources and multi-source,and meet unified management and efficient data retrieval requires under the distributed data storage environment,a distributed resources of catalog system structure is designed and implemented by using LDAP.Based on these,aimed at the problem of low query rate among servers the application of the shortest path algorithm to improve query rate method is proposed.Experimental results show that the use of the LDAP protocol achieve a distributed resource directory storage and management,application of the shortest path algorithm can significantly improve the efficiency of the distributed resource directory inquiries.
