基于MPLS的VPLS技术分析

VPLS是一项利用MPLS实现跨域广域网提供LAN业务的技术，它使得在基于包交换的网络架构上．可以实现多点服务，适应了网络发展的需要。从各个角度出发介绍了VPLS的原理、关键技术，在文章的最后，还给出了一个具体的网络实例来进一步解析VPL5的机制。对于要想了解VPLS的读者而言，具有一定的参考价值。

Analysis of VPLS Technology Based on MPLS

VPLS is an alternative technology based on MPLS to offer LAN services over WAN.It enables Ethernet multipoint services over a packet network infrastructure,which satisfies the development of the network.To show the concept of VPLS,this article gives a special analysis about VPLS on several points,including its principle,key technologies.And finally,it goes one step further by offering an instance to explain the mechanism of VPLS.It is a good reference for those who want to learn something about VPLS.
