摘　要21世纪是一个以数字化、网络化与信息化为核心的信息时代。信息技术的高速发展使得网络的法杖非常迅速。随着计算机网络的不断发展和普及，计算机网络带来了无穷的、免费的资源，但随之而来的安全问题也显得尤为重要。尤其对于企业，企业信息的泄漏，将有可能导致十分严重的后果。本文主要致力于安全高效企业专用网的设计与实现。阐述了安全高效企业专用网的设计方案。在充分了解以太网的组网方式后，根据现如今企业网的情况，结合网络安全技术，设计出安全高效企业专用网的模型，并对局域网内部进行细化。根据设计需要，这里使用PT模拟器以及GNS3模拟器共同实现网络功能，其中包括访问控制、VPN等；根据如今智能大厦的布线情况，设计出符合现实情况的综合布线系统。关键词：网络工程；局域网；网络安全；企业网AbstractIn the 21st century is a digital, network and information into the core of the information age. With the rapid development of information technology makes the network of staves very quickly. With the continuous development of computer network and popularization, the computer network has brought endless, free resources, but the resulting security problem also becomes very important. Especially for the enterprise, the enterprise information leakage, will likely lead to very serious consequences.This article is mainly engaged in the design and implementation of effective enterprise private network security. In this paper, the design of the effective enterprise private network security solutions. After a full picture of the Ethernet network mode, according to the situation of nowadays enterprise network, combined with the network security technology, design a safe and efficient enterprise private network model, and the internal refinement. According to the requirements of the design, the use of PT simulator and GNS3 simulator, realizing the function of network, including access control, VPN, etc.; According to the situation of todays intelligent building cabling, designed in accordance with the reality of the integrated wiring system.Keywords：network engineering Local area network (LAN) Network security Enterprise network第1章绪论1.1课题背景1995年Internet概念的提出，1996年Internet的崛起和1997年基于网络的分布式计算和应用分别被成为网络的第一、第二和第三次浪潮。由此可见Internet发展之快及其应用之广泛。据统计美国企业采用Internet的比例已高达46.6%，有70%的企业打算在几年内建立自己的Internet。据美国产业工会联合会（CIO）调查统计在1998年底之前所有财富500强企业都建立了Internet，其中近100家企业要求几乎所有的工作都基于WEB进行。当Internet刚刚提出时，主要应用于政府部门和企业的管理部门。随着Internet/Intranet技术的发展，Internet的应用
