浅谈光传送网ODUk SNCP保护故障处理

在OTN网络中ODUk SNCP子网连接保护被作为一种基本的保护方式而使用,ODUk SNCP提供ODU1级别以上的业务保护,因此OTN网络维护中,ODUk SNCP保护倒换状态检查是日常维护的重点。本文通过华为OSN 6800/8800设备介绍了SNCP保护倒换原理,从故障定位处理着手,分析了ODUk SNCP常见故障的原因及处理方法,并以典型故障为例,详细叙述了处理步骤和故障总结,为0TN网络中ODUk SNCP维护提供了参考。

In OTN network,ODUk SNCP sub network connection protection as a basic way to protect and use ODUk SNCP to providebusiness protection above the level of ODU1,so OTN network maintenance,ODUk SNCP protection switching state examinationis the focus of daily maintenance.This paper introduces the principle of SNCP protection switching through the HUAWEI OSN6800/8800equipment,from processing to fault location,analyzes the causes of common faults of ODUk and SNCP processingmethod,and taking the typical fault as an example,detailed description of the processing steps and fault summary,provide a referencefor OTN network ODUk SNCP maintenance.
