一种基于隧道性能分析的VPN分类方法

目前VPN技术应用的难点在于根据实际情况与需求选择合适的VPN技术方案。通过对VPN技术进行分析，指出了其关键技术在于隧道机制。通过对不同VP技术的隧道机制对网络性能影响进行分析，就可以得出不同VPN技术实现的差别，从而根据实际的网络情况与用户的需求，选择适合的VPN实现方案。最后。提出了一种基于隧道网络性能分析的VPN分类方法，在实践应用中证实了分类的有效性。

A Kind of VPN Classification Based on the Performance Analysis of Tunnel

For using the resource of public network as more as possible, and implementing it as internal network, the advent of the VPN satisfies these requirements. By analyzing several ways in implementing of mainstream VPN, it points out that he key of VPN is the mechanism of tunnel. So according to analysis the various performance of network that caused by various mechanism, we can conclude the differentia in technical implementing of VPN. At last this paper poses a method which is based on the performance analysis of tunnel for VPN classification. It works well in the real network and approves the validity of it.
