摘要
针对SPB协议网络中的分布式设备在发生故障时引起的用户数据转发中断的问题,文中采用NSR技术,将主控板上的SPB协议数据进行报文封装,利用高可靠性机制进行板间通信,实现实时数据备份。模拟实验表明,当主控板发生故障时,备用主控板升级为新主控板,恢复备份数据,不会引起用户数据转发中断。
SPB＇s distributed network equipment causes data forwarding interruption in the event of a failure. To solve this problem, this paper proposes a new non-stop data forwarding technology, NSR. By this technology, the SPB data on the control board is encapsulated, and communication between boards is done by reliable mechanisms and thus real-time data backup is achieved. Simulation shows that the standby board will become the control board when the control board breaks down to restore the backup data, thus avoiding the interruption of data forwarding.
