基于 BFD 检测的 IP 快速重路由机制

摘要

IP network is widely applied in internet nowadays, Further be applied in a variety of telecommunications service bearing. but the design principles of the traditional IP network is to provide the service of best effort, and can’t meet the high reliability requirements of real-time business such as IP telephone and video conference. This paper will introduce the IP FRR of BFD rapid detection mechanism, which is presented to repair failure rapidly, reduce the packet dropout. And also the detection technology of BFD and the principle of IP FRR will be introduced in detail. At last, the result of experimentation is provided.%　　 IP 网络目前被广泛应用在互联网中，更进一步被应用在各种电信业务的承载中。但传统 IP 网络的设计原则是提供“尽力而为”的服务，已很难满足现今 IP 电话、视频会议等实时性业务对网络高可靠性的要求。介绍一种结合 BFD 快速检测机制的 IP 快速重路由技术，能够实现对网络故障的快速修复，减少丢包，详细阐述 BFD 检测技术及 IP 快速重路由的实现原理，并通过实验进行测试验证。
