摘要:

BFD协议作为一种双向转发检测机制,可以提高故障检测速度,为链路间故障快速修复提供保障。为了在IPRAN路由设备传输实时业务时,能够对相邻设备间通信故障进行快速检测,并对检测到的故障迅速修复,本文设计讨论一种基于BFD和路由协议间联动机制,应用BFD双向转发检测功能,实现主备路由毫秒级的快速切换,从而快速修复网络故障,提高IPRAN组网的可靠性。

关键词: BFD, 路由协议, 毫秒级, 快速切换

Abstract:

 BFD(Bidirectional Forwarding Detection) protocol is a mechanism which can improve the rate of detecting trouble and provide a guarantee for quickly repairing trouble among links. In order to quickly detect the trouble of adjacent devices and repair the faults while transmitting real-time traffic in IPRAN routing device, this paper discusses a mechanism between BFD and routing protocols, which deploys BFD to realize fast switching between master and backup routing in milliseconds, and repairs the network problems, improves the reliability of IPRAN network.

Key words:  BFD, routing protocol, milliseconds, fast switching
