校园无线网络设计方案

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IEEE802.11g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DesignSchemeOfWirelessNetworkOfTheCampusAbstract:ThispaperhasintroducedthewirelesscampusnetworkplanningofmiddleschoolofLiYangandimplementingscheme.Providetheconstructionobjectofcampusnetworkanddesignrulesatfirst,proposetheensemblearchitectureofcampusnetworkandimplementingschemeonthisbasis.Accordingtothecurrentsituationthatthenetworkdevelopsatpresent,thebackboneofthenetworkadoptsgigaEthernettechnology,thenetworkofworkgroupadoptsthewirelessnetworktechnologyofIEEE802.11g.Inbackboneofthenetwork,designthreekindsofdifferentnetworkschemes,andmakecomparisonstothemseparately;Innetworkofworkgroup,explainwirelesscharacteristic,transmissionmedia,mainwirelessprotocolstandardofLAN,topologystructureandsecurityissuemainly,concreteproblemofdesigningetc.thatandhasprobedintothewirelessonlinesecurityandaccesspoint.Keywords:campusnetwork,networkplanning,wirelessLAN,wirelessnetworkprotocolstandard,wirelessnetworksecurityI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.........................................................93.4.3.1IEEE802.11系列协议...................................................93.4.3.2蓝牙标准.............................................................103.4.3.3家庭网络的HomeRF标准................................................103.4.3.4HyperLAN/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.............................................................164.3.3UPS电源方案.............................................................17第五章应用系统方案...............................................................195.1Internet/Intranet应用.......................................................195.2Internet访问方式............................................................20第六章无线网络安全方案...........................................................216.1无线网络安全概述.........................
