摘要
针对VRRP主用设备出现故障时,备用设备只能依赖设置时间来判断是否需要抢占,切换时间一般在3～4s之间,无法达到秒级以下的切换速度。为了提高VRRP的性能,提出由监测模块对VRRP路由器的链路状态、网络状况等进行快速检测,实现VRRP与监测模块联动,优化VRRP的切换效率。设计方案经测试可以使VRRP切换速度达到秒级以内,大大提高了设备的性能。
When master device of VRRP is failed, the backup device can only rely on the timeout time which was set before to determine whether it should seize. chieve the switching speed below second. In order to Generally the switching time is 3 to 4 s. It can＇t aimprove the performance of VRRP, the linkage function of VRRP and monitoring modules was proposed, by the monitoring module detecting the VRRP router link state and the network conditions rapidly. So the efficiency of VRRP switching was optimized. The test result shows that VRRP switching speed can be achieved within second level by testing, and the device performance was greatly improved.
