VPN隧道封装性能分析与研究

Analysis and Research of VPN Tunnel Encapsulation Performance

隧道技术是实现VPN的关键技术。本文分析了ESP和AH隧道协议在通道模式和传输模式下的隧道结构 ,计算了不同隧道的封装开销和开销比例 ,并对计算的结果进行了分析。

Tunnel technology is the key technology to realize VPN.This paper analyses the tunnel structure of ESP and AH in the channel mode and transportation mode,calculates the encapsulating payload and it's ratio of different tunnel,at last makes a research of the results.
