Method for control data synchronization of business modules in a stack system(Chinese)
-
摘要: 提出了一种弹性堆叠系统中控制业务模块在主备设备间进行数据同步的方法，确保主设备上各个业务模块数据能够按照指定的次序安全可靠的同步到备设备上，为业务模块的温和重启提供保证，从而保证堆叠系统转发不中断.同时也提出了一种数据同步的方法，通过定时检测同步消息通道，再结合异常序列号确认，既可以保证同步的可靠性，也可以保证同步效率.通过实验证明，此方法能保证堆叠系统实现无中断转发.Abstract: This paper defined a set of architectural and modeling to send data from stack master equipment to stack slave equipment in regular sequence in a stack system, to achieve graceful restart and non-stop forwarding. A method for batch data synchronization was presented, with the help of message channel detection and sequence number confirmation, it can improve the efficiency and reliability. The running results showed that this architectural and modeling totally satisfied the design requirements of non-stop forwarding.
