基于VPN技术的内部网络构建

虚拟专用网(VPN)是利用公共网络构建私有专用网络的技术,通过附加的安全隧道、用户认证和访问控制等技术,实现与专用网络相类似的安全性能的虚拟专用网络。无论是企业还是高校都希望能够构建一种网络,既确保安全,又便于维护。VPN能够帮助企业通过一个公用网络建立一个临时的、安全稳定的通讯隧道,使用这条隧道可以对数据进行几倍加密达到安全使用互联网的目的。本文结合几种VPN技术设计了一种内部网络的构建方案,既保证了协议之间的兼容,又实现了安全传输。

The Construction of Internal Network Based on VPN Technology

Virtual Private Network(VPN) uses public network technology to build a private dedicated network,and achieves the virtual private network with the similar security with private network through the additional security tunnel,user authentication and access control technology.Whether business or universities all hope to build a network which can ensure safety and maintain easily.VPN can help companies establish a temporary,safe and stable communication tunnel through a public network,and this tunnel can be use...
