VPN技术及其在数字社区的应用

VPN Technique and Its Application in Numerical Community

在阐述VPN及其关键技术——隧道技术的基础上,重点分析了数字社区网络安全布局结构及其设计技术,提出了实现数字社区VPN的MPLSVPN和嵌入式VPN模型,并分析了两种模型的应用特点。提出的数字社区网络安全模型具有经济适用、安全可靠、易于实现的特点,是适用于大、中型数字社区的网络安全解决方案。

On the basis of telling of VPN and its key technique-tunnel, the security framework design of numerical community and the theories were expatiated. And then two kinds of numerical community VPN model-MPLS VPN and embedded VPN were declared, and their application characteristics were elaborated. The security frame- work of numerical community being presented in the paper has the character of economical application, credible security and easy realization. For these characteristics, the framework being a safe solution of network is suitable to big and medium-size numerical community.
