摘要
灾难备份技术是保证TDCS/CTC系统高可用性和高安全性的重要技术基础,对保证铁路运输调度指挥连续运行具有重要意义。研究分析了TDCS/CTC系统的备份现状及存在的安全风险,对各主流灾难备份技术进行了介绍,设计了基于IBM技术的异地灾难备份方案和数据迁移方案,并对方案进行了实验室仿真测试。
The disaster backup technology is a key basic technology to ensure the high usability and high safety of TDCS/CTC system and also plays an important role in guarantying non-interrupted operation of the train operation dispatching and command system.The paper analyze the current status and existing safety risk of data backup technology used in TDCS/CTC system and present the main technologies for data backup widely used.Then a remote backup and data migration solution based on IBM technology is proposed,which has been successfully simulated and test in the lab.
