摘要
从高端路由器的可靠性出发,提出提高可靠性、减少故障持续时间的关键在于减少路由器主备倒换时间。文中通过对传统的主备倒换与热备份下的主备倒换进行比较,分析了热备份下的主备倒换在节省业务板和路由板的重启时间、业务板恢复配置时间、路由板路由学习聚合时间等方面的优势。同时详细介绍了基于热备份的主备倒换在高端路由器中的主要实现步骤,并对其技术特点和给用户提供的解决方案进行了阐述。
The paper started with high reliability of router,pointed out the key point of reliability is cutting down standby time in router.Then the paper compared the trait of cold standby and hot standby,discussed advantage of hot standby in cutting down reboot time of custom board and route board,recover configuration time of custom board,and study router items time of router board.Finally the paper presented application and feature of swap based on hot standby in router.
