基于事务的指挥所无中心分布式数据复制技术

摘要

针对指挥所内数据备份的问题，提出一种适用于指挥所内的基于事务的无中心分布式数据复制技术。该技术通过采用基于事务的串行化调度算法、基于事务的本地节点数据更新机制，建立无中心的分布式数据复制架构，实现分布式数据访问中间件。实验结果证明分布式数据访问中间件满足无中心数据复制要求，并具备较高的数据复制性能指标。%In order to solve the problem of Data Backup in Command Post,A technology suited to command post of ceterless distributed data replication war proposed in this paper. The technology Builded a Ceterless Distributed Data Replication Architecture ,and developed distributed data access middleware by the algorithm of serializable schedule base on transaction and by the algorithm of adaptive node selection. The result of test proved that distributed data access middleware satisfying data ceterless replicative requirement and has higher performance of data replication.
