| 摘要: |
| 环网保护是ITU-T和IETF联合工作组正在研究的多协议标签交换传送应用（MPLS-TP）关键技术之一。在研究现有的环网保护方案的基础上，提出了一种新颖的快速“Wrapping”环网保护倒换机制以及对应的分布式实现方式。运用这种快速的“Wrapping”环网保护倒换机制及其对应的分布式实现方式，可以降低在保护倒换中数据的丢失率。同时，分布式实现方式易于增加保护组容量，简化网络管理操作，增强设备可靠性。 |

| Abstract: |
| Multi-Protocol Label Switching Transport Profile(MPLS-TP) ring protection is one of the key technologies of MPLS-TP network which is still ongoing researched under a Joint Working Team(JWT) of ITU-T and IETF. Through investigating existing ring protection schemes,a novel “Fast Wrapping” ring protection switching mechanism and corresponding distributed implementation method are proposed. Using the “Fast Wrapping” switching mechanism and corresponding distributed implementation method,the data loss can be decreased during the protection switching. At the same time,the protection group volume will be easily increased,the operator of network management will be simplified and the equipment reliability will be improved due to the distributed implementation method. |
| Key words: MPLS-TP ring protection protection switching fast "Wrapping" distributed implementation |
