基于MPLS的VPN在光网中的实现

Realization of VPN based MPLS in Optical Network

虚拟专用网(VirtualPrivateNetwork:VPN)是网络互联技术和通信需求迅猛发展的产物,而MPLS(Multi-ProtocolLabelSwitching:多协议标记交换)是打开进入新世纪VPN技术之门的“钥匙”。MPLS属于下一代网络(NGN)架构,是IP高速骨干网络交换标准,MPLS使服务供应商能够提供端到端的高度可扩展的、分级别的商业IP业务,而且服务供应商和用户的配置和管理更加简单。本文提出了一种新的把MLPSVPN应用在光网络中的方法。

VPN is an outcome of the technique of Internet and the communication need fast fierce development. MPKS （Muhi-Protocol Label Switching） is ＂key＂ that opens the door of entering the new VPN technique of century. MPLS belongs to the next generation network （NGN） structure, is an exchange standard of IP high-speed backbone network. MPLS can make the Internet Service Providers（ISPs） carry the height expansive, classifiable IP businesses with the QoS of end to end, and the ISPs and customers can more simply deploy and Inanage network. The paper put forward an new method in which MPLS VPN is applied in Optical network.
