摘　　要：随着电信业务的迅猛发展,融合正在成为通信行业发展的主旋律。作为传送平面融合的新技术——T-MPLS满足了下一代传送网高速率、多业务、高性能的需求,是下一代传送分组网的发展趋势。本文在T-MPLS研究现状的基础上,分析了现有传送技术面临的问题,归纳并总结了T-MPLS的各项关键技术,包括其转发行为、生存性机制、OAM机制等,提出了目前研究的缺陷与不足并指明了进一步研究的方向和重点。With the rapid development of telecommunication services, the convergence between the different layers has become the main developing trend of communication field in the future. As a new convergent technology about the transport plane, T-MPLS meets the many requirements of the next generation transport packet-based network, such as high speed, multi-services, good performance. Based the newly research on T-MPLS technology, this paper analyses the problems the transport technology exits today, summarizes different key technologies of T-MPLS, including forwarding behaviors, survivability mechanism, OAM mechanism and so on. It also presents the shortcomings in the study and illustrates the direction of future work program.
