多协议标记交换VPN的加密与封装技术

Encrypting and Encapsulating Technology of MPLS VPN

分析了目前 VPN技术存在的问题 ,提出了基于多协议的标记交换 ( MPLS)技术 ,在公用骨干网上利用 IPSEC在客户路由器端加密 ,再在 MPLS边缘路由器端进行数据封装构建 VPN的思路及实施技术 ,解决了信息不能自动加密。

This paper analyzes the current problem of Virtual Private Network(VPN) technology, presents the thought and implementing technology of encrypting the data by IPSEC at Customer Edge (CE) router and encapsulating the data at Provider Edge (PE) router to construct the VPN based on Multi- protocol Label Switching(MPLS) technology at MPLS backbone. The problem that data can't be encrypted automatically, information leaking due to missending or disconnecting has been resolved.
