摘　　要：为满足ITU-T标签本地化的要求,讨论了一种改进型的基于Wrapping保护的环网保护方案,详细论述了通路建立与倒换机制,介绍了相关功能模块的架构,并对保护倒换时间进行了测试验证。该环网保护方案的保护倒换时间满足工程应用50 ms要求,可为分组传送网承载业务提供有效的网络级保护。In order to meet the requirement of ITU-T label localization,an improved ring protection program based on Wrap-ping protection is discussed. The pathway creation and switching mechanism are introduced. The architecture of function modules is introduced and the protection switching time is tested. The protection switching time of the ring protection mechanism could meet the requirement of 50 ms,and it can provide effective network-level protection for bearer service of packet transport network.
