摘要
讨论了用户对VPN的普遍需求、隧道技术机制对构建VPN的重要作用 ,以及为提供VPN的通用安全业务 ,隧道机制应该满足的功能和性能基本需求 ,按VPN的构建原理讨论了VPN的分类 .
Starting with the technical framework for constructing a VPN, authors discussed common requirements of users for VPN, the important role of tunnel mechanisms in constructing a VPN, and the essential reguirements that the tunnel mechanicsm should satisfy in funotion and performance for providing general secure application of a VPN. At the end, based on the contructing rules, the VPN classification was discussed.This article also interpreted what is VPN, how to construct a VPN, and which services a VPN can support. It would be useful to clarify our faint concept about VPN.
