一种新型的宽带网络技术—MPLS

A new technology of wide band-MPLS

介绍多协议标签转换(MPLS)是当前宽带通信领域新兴的热点技术之一,它是一种将第三层路由和第二层交换相结合的IP交换技术.为了解MPLS,结合标签、转发等价类、标签路由器和标签交换路径等MPLS的核心技术对MPLS的体系结构及其协议进行了分析和研究.

MPLS is one of the highlight technolo gies of wide band.In this paper,some analysis and researches on its framework and protocol are mad e through discussing some key technologies of MPLS such as Label,FEC,LSR,LSP and LDP.
