摘要

为解决原有基于G.8132协议的Wrapping保护机制下的环网保护标签维护管理复杂的难题

提出了一种改进的基于Wrapping保护机制的环网保护方案

详细论述了环网保护业务通道的建立与倒换机制

介绍了相关功能模块的架构

并且测试验证了保护倒换时间。该环网保护方案的保护倒换时间足以满足50ms的工程应用要求

因此可为PTN（分组传送网）承载业务提供有效的网络级保护。

Abstract

In order to solve the problem of the label maintenance and management for the ring protection based on G.8132 protocol and the Wrapping protection mechanism

an improvement ring protection program is proposed.The pathway creation of ring protection and the switching mechanism are introduced

as well as the architecture of function modules.The switching time of the ring protection is tested.It turned out to be that the switching time of the ring protection mechanism could meet the requirements of 50 ms on the engineering application.Therefore

it can provide effective network-level protection for bearer service of the Packet Transport Network（PTN）.
