摘要

生存性是光传送网（OTN）的一个重要研究课题

文章介绍了OTN数字包封帧结构中用于故障监测和保护倒换的字节安排;以基于ODUk的OTN环网保护为例

重点分析了在OTN环网保护中近侧倒换和远侧倒换时的APS信令传递机制.

Abstract

Survivability is an important research subject of optical transport network（OTN）. This article introduces the bytes used for fault monitoring and protect switching in the frame structure of digital wrapper. As an example

this article analyzes the convection mechanism of APS signaling when near-side & far-side switch occurs in the OTN ring protection based on ODUk.
