基于隧道技术的VPN在SCADA系统中的应用

Application of VPN Based on Tunneling Technology in SCADA System

针对局域控制网络无法满足SCADA系统远程监控与信息互联需求的现状,提出了利用VPN技术通过公共网络实现SCADA系统控制网络延伸和信息网络互联的解决方法;对VPN中的隧道技术以及无线VPDN的实现进行了分析与论述,通过系统应用实例论述了隧道技术以及VPN在SCADA系统中的应用与集成方法,验证并总结了基于隧道技术的VPN应用于SCADA系统的可行性、适用性和可推广性,同时结合公共网络和SCADA系统的发展趋势对基于隧道技术的VPN在SCADA系统中的应用前景进行了展望。

According to the fact that the local area control network is unable to meet SCADA systems needs of remote monitoring and information intereonnection, this paper proposes a new solution to extend control networks and interconnect information networks through public networks by using VPN technology. We not only have an analysis and discussion of tunneling technology, wireless VPDN and the methods used in SCADA systems, but also verify, summarize and look ahead the feasibility, applicability, replicability and prospects of the VPN based on tunneling technology in SCADA system application.
