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。
In order to solve the problem of high-speed information sharing in large-scale distributed management information system, a management information system platform based on peer-to-peer structure is proposed. The node model, management strategy and information sharing process of the system platform are given. A high-speed retrieval method based on distributed hash table and clustering is proposed to ensure that the user can quickly and accurately retrieve and control the distributed management system In order to ensure the distributed multi-copy synchronization in distributed management information system, “Peer lock” is proposed as the data consistency maintenance method. At the same time, a concrete realization method of the platform is given and an example is given. The experimental results show that the platform has good information sharing performance, efficient search capability and considerable fault tolerance.
