摘要
隧道技术是实现VPN的关键技术。常见的隧道协议包括GRE、L2TP和IPsec。不同的隧道协议具有不同的隧道结构,它们在工作模式、多路复用、安全性等方面的支持程度也不同。本文的研究结论为合理选择隧道技术提供了理论依据。
Tunneling is the key to implementing VPN. Common tunneling protocols are GRE, L2TP and IPSec. Different protocols have different tunnel structures, and have different support for work modes, such as security tunnel configuration and establishment , tunnel management and maintenance, multiplexing, multi-protocol transport, packet sequence and quality of service. The research result can help us choose a proper tunnel technique to implement VPN.
