摘要

传送多协议标签交换（MPLS）（T-MPLS）体系（TMH）是目前传送网技术研究的主要热点之一。随着IP技术的迅速发展和在服务质量（QoS）提高方面的需求

MPLS是重要解决方案。当前的传送网依然是以基于时分复用（TDM）技术为主（例如SDH）的光传送网络。如何在现有传送网上传送MPLS客户信号

是大家非常关注的问题。由于网络互连互通的需要

对于网络互连的接口必须要有统一的规范。文章重点介绍TMH的接口规范

包括TMH接口位置、网络节点接口（NNI）的基本信号结构、T-MPLS NNI接口的信息结构、T-MPLS的标签、复用和映射原则以及T-MPLS接口的物理层规范等。

Abstract

Transport MPLS（T-MPLS） hierarchy（TMH） is the key point in recent transport network technology study.MPLS is the important solution for IP technology and increase of QoS.Current transport network is still TDM based（e.g.SDH） optical transport network.How to transport MPLS client in exist transport network

every one is taking care.Since the requirements of network interconnection or interwork

the uniform specification of interfaces is necessary.The specification of TMH interfaces were introduced in this paper

include location of TMH interface

NNI basic signal structure

information structure for T-MPLS NNI

T-MPLS labels

multiplexing and mapping principles and physical specification of the T-MPLS interfaces etc.
