A Smooth Cutover Scheme for Operator-level Edge Routers
For communication operators,some customer edge routers have outdated performance and high failure rates,which affect the reliability and scalability of business carrying,and urgently need to be upgraded and replaced. A pair of routers usually use a hot-backup mechanism to provide redundancy in practical applications. When replacing,it is necessary to replace both hot-backup routers simultaneously and minimize the impact on downstream services. It proposes a novel replacement solution for edge routers from Cisco brand. By converting backup routing protocols,smooth cutover of routers from different manufacturers can be achieved in engineering,reducing the number of cutovers and construction costs without affecting downstream services.
