中小型企业网络拓扑搭建阳阳公司企业网的组建规划摘要现今的计算机网络技术飞速发展,使用网络进行信息传输已成为社会运行的一种基本方法。越来越多的计算机连接到不同的网络中,使计算机网络不论从结构上还是规模上都发生了很大的变化,这给计算机网络的建设提出了新的挑战,对实施网络工程也提出了新的要求。随着办公信息化、自动化的需求,各企业为提高办公效率,促进信息交流,为适应现代化办公的要求,企业网络的建设是企业向信息化发展的必然选择,企业网络系统是一个非常庞大而复杂的系统,它不仅为现代化企业综合管理和办公自动化等一系列应用提供基本操作平台,而且能提供多种应用服务,使信息能及时、准确地传送给各个系统。这直接关系到企业能否获得关键的竞争优势。本方案的主要目标是根据阳阳公司的局域网建设需求为背景,以计算机网络技术为基础,较详细地设计出该企业网络建设方案。因此本毕业设计着重从需求分析、企业网络的拓扑结构、设备的选型、网络安全设计、路由设计等方面进行了分析与描述,并给出了具体的设计方案。关键词:Internet;企业网;拓扑结构;端口汇聚;访问控制;VLAN人文科技学院计算机网络技术毕业论文3AbstractToday'scomputernetworktechnologyrapiddevelopment,theuseofnetworkinformationtransmissionhasbecomeasocietywhichisabasicmethodofoperation.Moreandmoreofthecomputerconnectedtothedifferentnetwork,computernetworknomatterfromthestructureorscalehaveundergonegreatchanges,thecomputernetworkconstruction,andputsforwardthenewchallengestoimplementnetworkprojecthasalsoputforwardnewrequirements.Asofficeinformatization,automationneeds,eachenterprisetoimproveofficeefficiency,promotetheexchangeofinformation,toadapttotherequirementsofthemodernoffice,enterprisenetworkconstructionistheenterprisetotheinevitablechoiceforthedevelopmentofinformatization,enterprisenetworksystemisaverylargeandcomplicatedsystem,itnotonlyformodernenterpriseintegratedmanagementandofficeautomationandsoonaseriesofappliedtoprovidebasicoperationplatform,butalsocanprovidevariousapplicationservice,sothattheinformationtimelyandaccuratelytransmittedtoeachsystem.Itdirectlyrelatedtotheenterprisecanobtainthekeycompetitiveadvantage.Theplan'smaingoalistoaccordingtothecompany'sLANYangconstructiondemandasabackground,basedonthecomputernetworktechnologyasthefoundation,adetaileddesigntheenterprisenetworkconstructionplan.Thisgraduationdesignmainlyfromrequirementsanalysis,enterprisenetworktopologystructure,equipmentselection,networksecuritydesign,routedesign,etc.,areanalyzedanddescribed,andthespecificdesignschemeispresented.Keywords:Internet;Enterprisenetwork;Topologicalstructure;Portconvergence;Accesscontrol;VLAN阳阳公司企业网的组建规划目录绪论...............................................................................................................................................1第一章企业网络需求分析...............................................................................................................21.1项目背景...........................................................................................................................21.2项目需求...........................................................................................................................21.3网络管理要求...................................................................................................................21.4编制依据.............................................................................................错误!未定义书签。1.5服务应用分析...................................................................................................................31.6服务器需求分析................................................................................................................3第二章网络系统设计.......................................................................................................................52.1网络设计要求...................................................................................................................52.2网络设计原则...................................................................................................................52.3设计目标.............................................................................................错误!未定义书签。2.4企业网络网拓扑结构图....................................................................................................52.5IP地址规划......................................................................................................................62.7ACL访问控制....................................................................................................................72.8STP生成树协议.................................................................................................................72.9VLAN端口划分及配置.......................................................................................................7第三章企业设备选型.......................................................................................................................83.1设备选型原则...................................................................................................................83.2核心层交换机选型............................................................................................................83.3接入层设备选型................................................................................................................83.4企业网服务器设备选择....................................................................................................93.5出口路由设备选型............................................................................................................9第四章交换机和路由器的配置.....................................................................................................104.1路由器与交换机的配置............................................
