IPSec VPN与MPLS VPN技术分析研究

随着电子商务、应用主机托管和多媒体通信等各种Internet应用的飞速发展，人们对网络的安全性也提出了越来越高的要求。而VPN技术的产生为解决安全问题提供了一条有效途径。目前，两种既各具特点又具有一定互补性的VPN架构正逐渐在网络领域大行其道，这两种VPN就是基于IP Security的IPSec VPN和采用MPLS的MPLSVPN。首先分析了这两种VPN的原理与实现及特点，然后进行了比较分析。

IPSec VPN vs. MPLS VPN

With rapid progress of Internet based application like e-business and multi-media communication,people recognize the importance of the Internet security than ever before.An effective way to guarantee the security of Internet is using VPN.So far two VPN frameworks are used,they are IPSec VPN which based on IP Security and MPLS VPN which use MPLS.In this paper,we introduce the implementation and features of these two VPN frameworks.And we also make a comparison of the two VPN frameworks.Then we get our conclusion based on our work.
