摘要:局域网就是局部区域范围内的计算机网络，可以理解为一组物理位置上彼此相隔不远的计算机和相关设备的互联集合，该集合允许用户相互通信和共享软硬件资源。局域网一般局限在几千米的距离范围内，可以包含一个和多个子网。随着社会的发展，对网络的利用范围逐渐扩大，不同地理位置之间需要进行大量的信息交流，相继出现了虚拟局域网（简称VLAN)，它是建立在交换技术基础上的，将网络上的节点按工作性质与需要划分成若干“逻辑工作组”，那么一个逻辑工作组就是一个虚拟网络。运用网络综合布线的知识，构建一个网吧局域网，通过交换机、路由器、服务器实现VLAN配置和管理，实现网络管理、网络互联以及资源共享。 网吧通常将若干台电脑组成一个局域网，然后通过ADSL、线缆或光纤等方式接入互联网。
本论文及方案是从国内网吧市场行业发展态势出发，为网吧业主提供网吧网络组建与管理比较优良的方案，为网吧业主在网吧何处落座、成本预算、网络设备的购买、如何组建布线、组装网吧和管理等问题上提供比较良好的参考方案，并且相关方面上也可为一些已经从业的网吧业主提供良好的建设性建议，为其网吧的升级和服务及将来的业绩发展提供不错的可行建议。在本方案设计中本方案使所有的网络设备，系统资源处于良好的运 行状态，达到用户预期的要求来设计的，不论从成本还是服务质量是都可圈可点 的亮点。

Abstract:LAN is a computer within the local area network ,can be interpreted as a group not far away from each other on the physical location of computers and related equipment interconnection collection that allows users to communicate with each other and shared hardware and software resources. LAN generally limited to within distance of several kilometers , can contain one or more subnets. With the development of society the use of the network gradually expanded the scope of the different geographical location between the need for a lot of information exchange, have appeared in the virtual local area network (hereinafter referred to VLAN),it-is built based on the exchange of technology will be on the network Click through the nature of work and needs divided into several “logical Working Group”, then of logic of the Working Group is a Virtual network . Knowledge of the use of network cabling, local area network to build an Internet cafe, through switches, routers, servers to achieve VLAN connectivity and resource sharing.
This thesis is from the domestic Internet market and industry development trend for the owners of Internet cafes, Internet cafes provide networking and management excellent scheme, for the owners of Internet cafes in Internet cafes where seating, cost budget, network equipment purchase, how to set up the wiring assembly cafes and management issues to provide a good reference program, and related aspects can also provide some practitioners have the owners of Internet cafes provide good suggestions for the Internet, upgrades and service and the future performance of development to provide good suggestions. this plan is in line with that all the network equipment, the system resources in good luck line status, to achieve the expected user to the requirements of the design, no matter from the cost or service quality is the highlight of all moments.
Key words: internet cafe; network cabling; manage; cost
在网吧竞争激烈的今天，网络质量的好坏直接决定了网吧的生存能力，因此如何组建网络质量较高的网吧，是网络经营者的必须要考虑的问题。能否组建一个优质的网络取决于网络拓扑结构设计、网络的综合布线和网络设备的选择。这个是从网吧网络组建方面考虑的，另外一方面也要考虑的是管理问题。
本论文将第二章中将在网络结构设计，硬件设备选择中展开，从网吧组建的整体思路、原则入手，对网吧组建的网络拓扑进行分析，着重论述网络接入层、网络汇聚层、网络交换层的设计，然后再此基础上，以一个小型网吧的项目进行展开介绍组建的过程和网络设备的选择和配置，以及关于网吧网络组建的成本分析，以说明组建网吧所需要的资金。
第三章中是关于网吧综合布线的过程，这里面包括电源布线和网络布线两大块，在这两大块中将分别进行有关的布线设计，布线施工，检测，验收等过程的介绍和说明。
第四章是关于网吧方面的经营与管理的问题，一个是经营，一个是管理。第五章是本论文的总结与对未来的展望。
