摘要： 摘要：为了解决大规模分布式管理信息系统中的高速信息共享等问题，提出了基于对等结构的管理信息系统平台。给出了该系统平台的节点模型、管理策略及信息共享流程；提出了一种结合分布式哈希表和聚类的高速检索方法，保证了用户能够在分布式管理系统中快速的精确检索和分类检索；实现了系统的用户透明；为了保证分布式管理信息系统中的分布式多副本同步，提出了“对等锁”作为数据一致性维护方法。同时，给出了平台的具体实现方法，并给出了实例；实验结果表明，该平台具有良好的信息共享性能、高效的搜索能力和相当的容错能力。

Abstract: Abstract: In order to deal with the distributed Management Information System(MIS) problems including fast information retrieval and so on, an information system platform based on Peer to Peer(P2P) structure was presented. The node model, the management scheme, and the information sharing flowswere given. In order to ensure the exact retrieval and the classified retrieval, an information search method based on distributed hash table and information clustering was given. In order to ensure the distributed multi-replica synchronization, a novel P2P multi-replica synchronization algorithm with a peer-to-peer lock was proposed. And the implement methodsand an instance system were given. Performance simulation results show that the platform can share information well, and has effective retrieval and fair fault-tolerant capabilities.

Key words: MIS, P2P, information sharing, retrieval, multi-replica synchronization
