摘　　要：复杂通信设备例如多业务交换机是通信网络的重要组成部分,设备内设计有多种板卡,支持配置不同的板卡提供不同的功能,其稳定、可靠直接影响到整个通信网络的稳定及可靠性,而保证设备中关键板卡在不影响业务处理前提下,平滑排除故障,恢复正常功能将是整个设备工作中的重中之重。因此提出了一种板卡热备份技术(HSP),在不需要配置和额外操作情况下实现板卡之间数据热备同步、自动切换。通过在多款设备上验证了该设计方法的有效性,采用该设计明显提高了设备整机的高效可靠性。Complex communication equipment,such as multi-service switches,is an important part of the communication network.There are many kinds of boards in the equipment,which support different configuration of boards and provide different functions.Their stability and reliability directly affect the stability and reliability of the whole communication network.To ensure that the key boards in the equipment can smoothly remove faults and restore normal functions without affecting the business processing will be the top priority of the whole equipment work.Therefore,this paper proposes a HSP(hot standby protocol)technology of boards,which can realize data hot standby synchronization and automatic switching between boards without configuration and additional operations.The effectiveness of the design method is verified on several types of equipment,and the high efficiency and reliability of the whole equipment can be significantly improved by adopting the design.
