摘　　要：多保护流量自动切换机制是针对多种上行传输方式的OLT设备制定的链路和业务的一种保障机制,基于VRRP、链路抢占等技术实现了OLT设备在故障中断、恢复后的业务自动切换;分析了传输中缩减中断时长提升业务质量的问题,优化了OLT设备上联链路结果,使OLT设备上行传输不仅具备了多种保护方式,同时还提升了业务质量,对宽带业务、IPTV业务等对传输要求较高的业务提供了保障。The multi protection traffic automatic switching mechanism is a guarantee mechanism for links and services developed for OLT devices with multiple uplink transmission methods.Based on technologies such as VRRP and link prcemption,OLT devices achieve automatic business switching after fault interruption and recovery;Analyzed the issuc of reducing interruption duration and improving service quality in transmission,optimized the uplink results of OLT devices,and provided multiple protection methods for uplink transmission of OLT devices.At the same time,it also improved service quality,providing guarantees for broadband services,IPTV services,and other services that require high transmission requirements.

关 键 词：VRRP 链路抢占 保护 可靠性 传输质量
