MPLS VPN是一种基于多协议标记交换(MPLS)技术的IP虚拟专用网络(VPN),是通过在网络路由和交换设备上应用MPLS技术,简化核心路由器的路由选择方式,并结合传统路由技术的标记交换来实现的。本文介绍了各种VPN技术比较和发展现状,凸出了MPLS VPN的优势。
MPLS VPN is an IP Virtual Private Network (VPN) based on Multiprotocol Label Switching (MPLS) technology. It simplifies the route selection of core routers by applying MPLS technology to the network routing and switching equipment. Combined with the traditional routing technology Mark exchange to achieve. This article describes the various VPN technology comparison and development status, highlights the advantages of MPLS VPN.
