在传统的移动承载网络中，通过MPLSL2V1，N技术来建立不同网元之间的连接。但是，这种基于MPLS的PW技术在许多场景下存在扩展性问题，包括端到端Tulmel数量多、LDPPeer数量大，以及对设备性能规格的要求高等问题。本文基于各路由器厂家设备的支持情况，提出了基于MPLS的多段PW技术来解决这些问题，重点介绍基于MPLS技术的多段二层Tunnel的原理与关键技术。

In the mobile network, the traditional technology is based on the MPLS L2VPN technology. However, there are many problems in many scenarios, such as the large amounts of end-to-end tunnel and LDP Peer, and the limit of the router performance. In this paper, we provide a new technology： the MS-PW. It can resolve the problems of traditional solution. This paper introduces the principle and key technology of MS-PW.
