Paxos 在 TDCS／CTC 数据分布式存储中的一致性研究

摘要

The system data of TDCS/CTC plays an important role in the reappearance of equip-ment and the analysis of data in future,but there are some defects in the system of storage tech-nologies,such as data storage disk damaged easily and reliability and consistency of data are not in high standard in only one copy redundancy circumstance.According to the current situation of TDCS/CTC backup storage technology,the distributed data storage model is proposed based on Paxos algorithm.After backup of the data,the traditional method and the cumulative digest value method are used to check the consistency of source data.The check results show that the model can achieve the consistency of the data.%TDCS／CTC 数据系统在重现设备状况和后期数据分析处理中具有重要作用，但是该系统的现有存储技术存在一些缺陷，比如存储磁盘易损坏，在冗余情况下，副本数仅一个时，数据的可靠性和一致性较低。针对 TDCS／CTC 备份存储的技术现状，提出一种基于 Paxos 算法的分布式数据存储模型。在存储备份完成后，采用传统法和累积摘要值法对其数据的一致性进行检测。检测结果表明，该模型能够达到数据的一致性目的。
