通信IP网作为实时业务传输载体,要求能够对相邻系统之间通信故障进行快速检测,在出现故障时可以快速切换到备份链路,以保证实时数据不间断传输。在研究BFD协议原理的基础上,根据通信IP网运行中出现的问题,应用BFD双向快速检测功能,实现了VRRP的Master/Backup状态毫秒级切换,并利用BFD会话检测静态路由所在链路的状态,实现一跳和多跳的静态路由自动切换,提高了通信IP网的可靠性。

The communication IP network as the real-time data transmission carrier,requires the capacity of quickly detecting trouble in the link of communication between two systems,and quickly switching to the backup link,in order to guarantee the incessantly transmission of real-time date.Based on the study of BFD and according to the problems which occurred in application of the communication IP network,deploys BFD to realize switching between VRRP master and backup in milliseconds,and automatically changing to backup route from main route in static-routing protocol using single hop detection or multi hop detection,increasing the reliability of the network.
