使用VPN技术实现陆梁自动化远程监控

TO REALIZE LOGN-DISTANCE AUTOMATIZATION SUPERVISORY IN LULIANG WITH VPN TECHNOLOGY

虚拟专用网(VPN)代表了当今网络发展的最新趋势,它综合了传统数据网络的性能优点(安全和QoS)和共享数据网络结构的优点(简单和低成本),并能够提供远程访问外部网和内部网的连接。目前VPN主要采用四项技术来保证安全,这四项技术分别是隧道技术(Tunneling)、加解密技术、密钥管理技术、使用者与设备身份认证技术。本文将重点介绍如何选择合适的隧道技术来实现陆梁自动化远程监控系统。

The virtual private network(VPN)represents the development tide of today's network.It synthesizes the advantages of traditional data network(Security and Quality of Servic)and shared data network structure(simple and low cost).It can provide remote access connection between outernet and intranet.At present,4 technologies are adopted in VPN to ensure security.They are tunneling technology,incipher-decipher technology,cipher key management technology and user & equipment identity authentication technology.This paper introduces how to select the suitable tunneling technology to realize automation process supervisory in Luliang.
