西安广播电视大学开放教育计算机科学与技术专业毕业论文(设计)题目:汉庭连锁酒店网络规划与实施专业层次:本科级别:2011年秋季学号:1161101257013姓名:左鹏分校(工作站):直属一分校指导教师:杨彩霖2013年5月10日摘要汉庭酒店是华住旗下标准经济酒店,致力于为商旅客人提供便捷的住宿体验。本设计方案是关于小型企业局域网的设计,设计方案分为三个模块:交换模块、Internet接入模块、远程访问模块。根据各部门职能不同把交换模块划分为不同的VLAN,从而减少了广播冲突提高了传输效率,通过部署ACL限制用户的访问,有效地保护敏感数据,提高了网络安全性。借助三层交换机的路由功能,可以实现各VLAN间数据包高速转发,解决VLAN之间的传输瓶颈。Internet接入模块功能主要通过路由器来实现,它的作用主要是建立外网和企业网的正常通信。使企业网的用户访问Internet同时Internet用户能在一定程度上访问企业网。通过配置NAT(NetAddressTranslation),不仅是企业网用户可以访问Internet,而且对外隐藏企业网内部地址,从而实现地址保护。远程访问模块是针对移动用户设计的。通过VPN(VirtualPrivateNetwork)技术可以在公共网络的两个端点间建立一条逻辑连接,使在外办公人员可以通过Internet访问公司内部网,极大地提高了办公效率,同时免去了高昂的专线租用费用关键词:企业网络;拓扑结构;冗余;路由AbstractTherapiddevelopmentoftheInternetisallovertheworldinformationindustryofenormouschangeandfar-reachingconsequences.Marketcompetitionhasbecomethetrendofglobalization.Forlargeenterprises,inadjustingthedevelopmentstrategy,musttakeintoaccountthemarket'sglobalcompetitivenessstrategy,andallthisinformationplatformwillalsobebasedontheprincipleoftheuseofcomputernetworksandnetworkplanningtechnologytothenetworkinordertoensurepatency.IntranetisaninternationalInternettechnologyintheenterpriseorwithinaclosedusergroupapplications.IntranetistheuseofInternettechnologies,especiallyTCP/IPprotocolandthecompletionoftheenterpriseinternalnetwork.Thistechnologyallowsinteroperabilityofdifferentcomputerplatforms,anddonothavetoconsideritsposition.Thatiswhattheusercanvisitanyorfromanycomputeraccess.Fromthestartthewholeenterpriseclassnetworkneedsanalysis,basedonthemainstreamstagecisconetworkequipmentcompanyselection,withthegoaltobuildthemostsuitablenetworktopology,designedwithnetworktechnology.AspartofthisimplementationtobuildthesimulatorGNS3networktopology,theuseofciscodeviceoperatingsystemsunzip-c2691-advsecurityk9-mz.124-11.T2forallequipmentwithinthecoretopologyIOS,routersandswitchesusingSecureCRTfortheconfiguration,andviewtheexperimentalresultstoverifythatthenetworkmeetsbusinessneeds.Keywords:Enterprisenetworks,Topology,Redundancy,Routing,Switching目录1前言...............................................................................................................11.1集团综合信息系统建设目标.............................................................................................11.2具体用户需求:.................................................................................................................21.3集团综合信息系统建设原则.............................................................................................21.3.1先进性......................................................................................................................21.3.2标准性......................................................................................................................21.3.3兼容性..............................................................................................
