摘要
双向转发检测(BFD,Bidirectional For-warding Detection)是一种快速检测IP网络链路和通道连接性的新型机制,为快速故障恢复奠定了基础,因而作为提高IP网络可靠性的关键技术之一得到了广泛的应用。文章介绍了BFD技术的协议及其典型应用,并对BFD技术与现有控制层面技术的配合使用进行了分析。
BFD is a new type mechanism used for detecting the connectivity of IP network links and channels. As one of the key technologies to improve the reliability for IP network, BFD technology is extensive applied and laid a foundation for rapid fault recovery. This article introduces the protocols of BDF technology and its typical application, and makes analysis on the collaboration of BFD and the existing control layer technologies.
