网络的灾备与故障恢复作为网络安全的一部分,一直以来是人们关注的重点,传统网络缺少自动化的网络故障检测与恢复工具。SDN打破了传统网络设计理念,实现了控制平面和数据平面的分离,并开放了网络的可编程能力,从而提高了网络的灵活性和可管控性。通过SDN技术,自动化的网络故障恢复与检测成为了可能。设计了一种基于SDN的链路故障检测与自动化恢复方案,通过链路发现协议来获得全网拓扑,监控网络链路状态,并通过SDN的集中管控特性和可编程性实现链路故障快速检测和故障恢复。
As part of network security,network disaster backup and recovery has been a focus,and traditional network lacks of automation failure detection and recovery too1. SDN broke the traditional network design idea,the separation of control plane and data plane was realized,and the network of programmable ability was opened. Based on SDN,automatic network fault recovery and detection has become a possibility. A link failure detection and automatic recovery program based on SDN was designed. The entire network topology could be obtained,and network link state could be monitored through link discovery protoco1. Through the centralized management and control features of SDN,fast detection and link failure recovery were achieved.
