T-MPLS分组传送技术

T-MPLS Packet Transport Technology

T-MPLS是一种基于MPLS的面向连接的分组传送技术,它为下一代传送网提供了一种统一的全业务解决方案。本文首先对T-MPLS的国际标准化进程进行了介绍,然后根据ITU-T和IETF相关建议和国内外的研究趋势,对这种新兴的分组传送技术——T-MPLS的体系结构、信号适配与传输、OAM和生存性方面取得的成果和存在的问题进行了阐述。

T-MPLS is a connection-oriented packet transport technology based on MPLS. h provides an integrated transport solution for all traffic types in the next generation transport network. This paper gives an introduction to the T-MPLS standardization process. Then according to the ITU-T and IETF recommendations and the international research trends, the architecture, signal adaptation and transmission, OAM and survivability of the new rising T-MPLS are described.
