中文摘要：

T-MPLS与MPLS域间互联的问题一直是业界研究和讨论的热点问题。分别介绍了两种T-MPLS与MPLS域间互联互通的方法：基于EVC（以太网虚拟连接）技术的域间互联互通方法和基于应用于TMPLS域的伪线（Pseudowires）技术的域间互联互通方法。并在此基础上对这两类方法的优缺点进行了分析和比较。

英文摘要：

The interconnection between TMPLS and MPLS domains has been the focus of research and discussion all the time. This paper gives an introduction to two solutions of interconnection between TMPLS and MPLS domains： one is the interconnection based EVC （Ethernet Virtual Connection）; the other is the inter-connection based on the Pseudowires applied to TMPLS domain. In this paper these two solutions are analyzed and compared. The pros and cons of each are described.
