基于MPLS的VPN的研究与发展

Research & Development of a VPN Solution Based on the MPLS

介绍了VPN的技术基础,分析了它在几个典型传统网络上的应用。概述了MPLS的基本原理及其特点,分析了在MPLS上建立VPN的优点和实现它的关键技术,并且提出了MPLS VPN有待解决的问题。

This paper describes the principle of the MPLS.IP QoS offers two different models,namely integrated services and different services.This paper gives an introduction on these two models and discusses how to realize IP QoS by using MPLS.Some challenges we are facing are discussed for reference in further designing and researching.
