摘要
本文从较底层的角度,阐述了如何使用MPLS技术实现PWE3仿真业务的处理流程。首先简单的介绍了PWE3和MPLS的基 本原理。然后重点放在了展示MPLS技术底层Labe1处理的大量细节。并以Ethernet和ATM的PWE3业务为例详细叙述了 底层LSR上MPLS处理单元为实现PWE3功能而进行的各种操作。
This paper ilustrate that how to implement the processing of Pseudo Wire Emulation Edge-to-Edge with Multiprotocol Label Switching technique in infrastructure. First. the principle of PWE3 and MPLS will be given. A great deal of basic details, that the operations of labels in the infrastructure of MPLS architecture, would be demonstrated secondly. However. two particular case are shown to describe a variety of operations which enable the MPLS process un it in the Label Switching Router to achieve the function of PWE3.
