T-MPLS的生存性机制融合了ITU-TY.1720建议中的MPLS保护倒换技术,制定了线性保护机制和环网保护机制。目前主流的PTN技术为T-MPLS技术。T-MPLS的生存性是分组传送网的一个重要特征,T-MPLS的生存性主要基于传送平面的保护倒换技术和基于控制面的恢复技术来实现。实现业务的快速保护倒换。
The survivability mechanism of T-MPLS incorporates the MPLS protection switching technology proposed in ITU-T Y.1720 and formulated a linear protection mechanism and a ring network protection mechanism. The current mainstream PTN technology is T-MPLS technology. The survivability of T-MPLS is an important feature of packet transport networks. The survivability of T-MPLS is mainly based on the transport plane protection switching technology and control plane based recovery technology. To achieve rapid business protection switching.
