VPN在大型企业网络中的应用研究

摘要：

随着信息技术的高速发展，大型企业对计算机网络的需求越来越高，促进了VPN技术快速的发展和应用。VPN有着租用专线的安全的和因特网廉价的优点。

本文具体分析了VPN技术的现状和发展趋势，介绍了VPN的产生、特征和优势。详细分析了大型企业对VPN的需求，结合实际应用背景给出两个解决方案，即基于IPSec VPN和MPLS VPN在大型企业中的部署方案，并详细地给出了它们的设计和实现方法。最后对IPSec VPN与MPLS VPN二种方案的进行了对比分析，给出了它们各自的适用的场景。

Research of Application of VPN in Large Enterprise Network

Abstract:

With the rapid development of the Information Technology, demand on network from large enterprises becomes larger and larger. All of this promotes the rapid development and application of VPN technology. VPN has the advantage of security which leased line possesses and the advantage of inexpensiveness which Internet possesses.

This paper analyzes the present situation and development trend of VPN technology, introduces the production, characteristics, advantages of the VPN. Then the paper analyzes the requirement of the VPN network construction of large enterprises. Afterward, two schemes are given according to practical background. One uses IPSec VPN, and the other uses MPLS VPN. The design and realization processes of the two schemes are given in detail. At last, this paper compares the IPSec VPN and the MPLS VPN, and points out the scenarios where each scheme is applicable. Key words: VPN; Enterprise network; IPSec VPN; MPLS VPN
