摘 要

随着计算机网络的发展和宽带接入的普及，各种网络应用将层出不穷，计算机在社会各个领域的应用和影响也早已渗透到了人们工作和生活的各个方面。经济效益是经营者必须首先考的问题。 根据网吧的需求为网吧选择一种实用的、可行的组网方式，将先进的技术转化成实用而经济的产品和解决方案，在投入同时既获得了可靠性和强大的性能，追求更高的投资效率是普通网吧经营者的共识。组网成本的高低当然是选择网吧组网方案的瓶颈。

本次设计主要是网吧组建及相关技术。首先讲述了一下网吧的发展及前景。然后，详细描述了网吧的网络设计。从网吧局域网规划，到网吧的网络结构、拓扑图，到网吧网络组建注意事项（包括网络布线，布线施工和检测），到最后的网吧网络安全方案都作了比较详细的讲解。接着也是本论文的重点，主要讲述了网吧服务器的配置，包括了DHCP、NAT重载、VLAN划分等，实验在PacketTrace仿真器上做，还有无盘系统，其中无盘系统的配置是本章的重点。最后简单地讲述了网吧设备的选型，包括了无盘系统，交换机，路由器既PC的选型。

ABSTRACT

With the development of computer network and the popularization of broadband access, various network applications will emerge in endlessly, and the application and influence of computer in various fields of society have already penetrated into all aspects of people's work and life. Economic benefit is the problem that the operator must first take an examination. According to the demand of Internet cafes, we choose a practical and feasible networking method for Internet cafes, and transform advanced technology into practical and economical products and solutions. At the same time, we can obtain both reliability and strong performance at the same time the pursuit of higher investment efficiency is the consensus of ordinary Internet cafes operators. Of course, the high and low cost of networking is the bottleneck of choosing the network scheme of Internet cafes.

This time The design is mainly the construction of Internet cafes and related technology. First of all, the development of Internet cafes and prospects. Then, the network design of Internet cafes is described in detail. From the network network planning of Internet cafes, to the network structure of Internet cafes, topology diagram, to the network construction of Internet cafes matters needing attention (including network wiring, wiring construction and detection), to the final network security scheme of Internet cafes explained in more detail. Then it is also the focus of this paper, mainly about the configuration of Internet cafes server, including DHCP、NAT overload, VLAN division and so on, the experiment is done on the PacketTrace simulator, there is no disk system, among which no disk system. configuration is the focus of this chapter. Finally, a brief description of the Internet bar equipment selection, including the diskless system, switches, routers PC selection.

Keywords:Internet cafe; networking; diskless technology; VLAN;PacketTrace
