| 摘 要： | 随着3G移动通信系统IP化和面向IP的全业务时代的到来,城域传送网络正面临着由基于电路交换的SDH网络向基于分组交换的电信级分组传送网（PTN）的逐步演进趋势。保护是PTN满足运营商级需求的重要特性。本文介绍了PTN各种保护机制,重点针对应用在移动回传网络中的PTN环网保护方式进行了探讨,并对各种故障类型触发保护的实现机制进行了分析。

The Ring Protection Switching Mechanism of PTN |

| Abstract: | As the IP-oriented mobile communication system of 3G and the IP-oriented full-services periods are coming, the metro transport network are suffering an gradually evolution from SDH network based on the circuit switch to the telecom-class Packet Transport Network (PTN) based on the packet switch. Protection is an important characteristic of PTN to meet the carrier-class needs. All kinds of protection mechanisms of PTN are introduced in this paper, and focuses on the ring protection that are proposed nearly f... |
