城域网MPLS VPN技术需求与引入策略

Demand and Introduction Strategy of MPLS VPN Technology in Metropolitan Area Network

MPLS(多协议标记交换)技术将ATM技术的可靠性和IP技术的灵活性巧妙的结合在一起,近几年呈现出较快的发展速度。当前我国各大城市中对于城域网建设的用户接入、网络分层、网络拓扑以及网络管理等都进行了优化。基于此,笔者将针对城域网MPLS VPN技术需求及发展现状、引入技术方案等进行分析,并以其在中移铁通城域网中的应用实例分析其实用性。

MPLS(Multiple protocol Label Switching)technology combines the reliability of ATM technology with the flexibility of IP technology,and shows a faster pace of development in recent years.At present,all major cities in China have optimized the user access,network layering,network topology and network management of metropolitan area network construction.Based on this,the author will analyze the demand and development of MPLS VPN technology in MAN,introduce the technical scheme and so on,and analyzes its practicability with the application example in metropolitan area network.
