摘要
在弹性堆叠系统中,主备设备都处于工作状态,对于实时操作系统,数据批量同步所在的进程优先级一般不是最高,主备设备间数据批量同步很难保证既快速又可靠。该文提出一种数据批量同步方法,通过定时检测批量同步消息通道,结合异常序列号确认,保证数据快速同步和同步可靠性,能在实时操作系统中很好地运行。
In flexible stack system, stack master and stack slave are all in working state, the process priority of data batch synchronization is not the highest, it is very difficult to synchronize data quickly and reliably between stack master and slave. This paper presents a method for data batch synchronization, with the help of message channel detection and sequence number confirmation, which can improve the efficiency and reliability, and it can run quite well in a real-time operating system.
