校园无线网络设计方案.doc

I校园无线网络设计方案摘 要： 本文介 绍了 XX 中学无线校园网规划及实施方案首先给出校园网的建设目标及设计原则, 在此基 础上提出校园网的总体结构及实施方案根据目前网络发展的现状，网 络主干采用千兆以太网技术，工作 组网络采用 IEEE 802.11g 的无线网络技术在网络主干方面,设计出三种不同的网络方案,并对它们分别作出比较;在工作组网络方面,主要阐述了无线局域网的特点、 传输媒体、主要无 线协议标准、拓朴 结构和安全性问题,并且探讨了无线网络安全及接入点设计等具体问题关键词：校园网,网络规划,无线局域网,无线协议标准,无线网络安全Design Scheme Of Wireless Network Of The CampusAbstract: This paper has introduced the wireless campus network planning of middle school of LiYang and implementing scheme. Provide the construction object of campus network and design rules at first, propose the ensemble architecture of campus network and implementing scheme on this basis. According to the current situation that the network develops at present, the backbone of the network adopts giga Ethernet technology, the network of work group adopts the wireless network technology of IEEE 802.11g. In backbone of the network , design three kinds of different network schemes, and make comparisons to them separately; In network of work group , explain wireless characteristic , transmission media , main wireless protocol standard of LAN , topology structure and security issue mainly, concrete problem of designing etc. that and has probed into the wireless online security and access point.Keywords:campus network,network planning,wireless LAN,wireless network protocol standard,wireless network securityI目 录第一章 需求分析 ......................................................................11.1 基本情况 .......................................................................11.2 功能和技术要求 .................................................................11.3 地域需求 .......................................................................21.4 系统维护和培训需求 .............................................................2第二章 设计原则和实现目标 ............................................................32.1 网络系统设计原则 ...............................................................32.1.1 先进性和实用性 .............................................................32.1.2 系统与软件的可靠性 .........................................................32.1.3 系统安全性与保密性 .........................................................32.1.4 易管理与维护 ...............................................................32.1.5 易扩充性 ...................................................................32.2 主要网络设备的选择原则 .........................................................42.2.1 安全、稳定、可靠 ...........................................................42.2.2 技术先进 ...................................................................42.2.3 便于扩展 ...................................................................42.2.4 管理和维护方便 .............................................................42.3 实现目标 .......................................................................4第三章 计算机网络系统方案 ............................................................63.1 拓扑结构选型 ...................................................................63.2 网络主干技术选型 ..............................................................63.3 主干组网技术选择 ...............................................................73.4 工作组网络选择 .................................................................73.4.1 无线局域网的特点 ...........................................................73.4.2 无线局域网的传输媒体 .......................................................83.4.2.1 微波技术 ...............................................................83.4.2.2 红外线技术 .............................................................83.4.2.3 无线电波 ...............................................................93.4.3 无线局域网协议标准 .........................................................93.4.3.1 IEEE802.11 系列协议 ...................................................93.4.3.2 蓝牙标准 ..............................................................103.4.3.3 家庭网络的 HomeRF 标准 .................................................103.4.3.4 HyperLAN/2 标准 ......................................................103.4.3.5 无线局域网标准的比较 ..................................................103．4 无线局域网拓扑结构 ...........................................................113.4.1 对等网络 ...................................................................113.4.2 结构化网络 ................................................................11II3.5 网络产品选型 .................................................................123.5.1 网络主干设计 ..............................................................123.5.2 工作组网络设计 ............................................................13第四章 主机系统方案 .................................................................144.1　 服务器选型原则 ...............................................................144.2　 服务器的选型 .................................................................144.3　 主机方案详细说明 .............................................................144.3.1 主机设备介绍 .............................................................154.3.2 主机容错方案 ..............................................................164.3.3　 UPS 电源方案 .............................................................17第五章 应用系统方案 .............。
