摘要：    当今社会的计算机网络技术飞速发展，灵活使用网络来进行信息的传输早已经成为社会运行的基本的一种方式。随着办公的信息化、自动化的需求，每个公司为了提升办公的高效率，力争促使信息更顺畅地交流，适应这个现代化办公的要求，就要组建公司内部的办公局域网。搭建公司局域网所涉及的各种方面很多，最重要的是需要一个整体的设计和规划，然后更要处理布线、网络设备选择的型号和配置，服务器的设备选择与配置、网络软件的安装等各种方面，这些都需要各就各位的慢慢实现，最后面还需要进行正常的日常性规律文护，在此就如何规划和设计这个公司的局域网进行简要描述。
首先从总体上开始对公司内网的建设和一般的国内外现象等各方面进行了分析与研究，然后对具体的内部局域网的需求进行一般的分析，确定公司网络拓扑的结构、综合布线设计原则、中心机房规划与设计、网络设备选择等。从多个方面对公司局域网建设提出了规划的方案，以期对公司局域网的建设做出贡献。课题提出了一个公司局域网与另一个局域网架设之间的问题，通过如上多方面的实际需求和分析，过程的进展中也遇到很多在之前实际生活中从没有遇到的多方面的困难，如DHCP中继与IPSec VPN的架设等问题，通过解决这些问题，得出了网络可以更加美好的结论。本文从网络的实用性方面对公司建设的内网进行了一般的研究，并详细介绍了使用到的设计和网络设备的一般关键操作。31497

Abstract:     With current rapid development of computer networks nowadays，the use of information transmission network has now become a newly basic way of operation．With the office of information and automation needs various of units to improve working efficiency and facilitate the exchange of real-time information , adapting to modern office requirements， the need for organizing enterprise office LAN. The formation of enterprises involved in all aspects of LAN lot， first of all that need a proper design and pLANning， and then have to deal with cabling， network equipment selection and the configuration， server equipment selection and configuration， network software installation， etc.， which require slowly one by one realized， finally， the need a normal day-to-day maintenance， here we focus on how the pLANning and design of enterprise LAN On．In this long paper， a whole-to-business network，subjects，thoughts and the status been at national or be abroad，I analyzed lots of technologies or so-called products ,and then the internal LAN to the specific needs of industry analysis will determine the enterprise network topology， the design principles of integrated wiring， Center, room pLANning and design, selection of network equipment. From all aspects of building enterprise LAN pLANning program， with a view to building on the enterprise LAN contribution．The topic mentioned a problem about how to operate a LAN-LAN network，though I did quit lots of demand analysis。Facing lots of problems I never met before，for example，DHCP relay and IPSec VPN，by solving those problems，I concluded a better future about network in the future. This passage also research about the usable of network on LAN building, and introduces the key operation on network facilities carefully.
