企业局域网建设规划研究

毕业设计（论文）报告纸i企业局域网建设规划研究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式。随着办公信息化、自动化的需求，各单位为提高办公效率，促进信息交流，适应现代化办公的要求，需要组建企业办公局域网。组建企业局域网所涉及的方方面面很多，首先需要一个正确的设计规划，然后需要处理布线、网络设备选型与配置、服务器设备选型与配置、网络软件的安装等方面，这都需要按部就班的逐一实现，最后还需要进行正常的日常维护，本文就如何规划和设计企业局域网进行浅述。本文首先从总体上对企业网的建设、目标、思路、国内外现状、技术和产品进行了分析研究，然后对具体业内部局域网的需求进行分析，确定企业网络拓扑结构、综合布线设计原则、中心机房规划与设计、网络设备选择等。从各个方面对企业局域网建设提出了规划的方案，以期对企业局域网的建设做出贡献。关键词：企业局域网，企业拓扑结构，网络设备选型，VLAN毕业设计（论文）报告纸iiPlanningStudyontheconstructionofenterpriseLANAbstractThecurrentrapiddevelopmentofcomputernetworktechnology，theuseofinformationtransmissionnetworkhasbecomeabasicwayofoperation．Withtheofficeofinformationandautomationneedsofvariousunitstoimprovetheofficeefficiencyandfacilitatetheexchangeofinformation，toadapttomodernofficerequirements，theneedfororganizingenterpriseofficeLAN.TheformationofenterprisesinvolvedinallaspectsofLANlot，firstofallneedaproperdesignandplanning，andthenhavetodealwithcabling，networkequipmentselectionandconfiguration，serverequipmentselectionandconfiguration，networksoftwareinstallation，etc.，whichrequirestep-by-steponebyonerealized，finally，theneedfornormalday-to-daymaintenance，thisarticleonhowtheplanninganddesignofenterpriseLANOn．Inthispaper，awhole-to-businessnetwork，objectives，ideasandthestatusquoathomeandabroad，technologyandproductswereanalyzed，andthentheinternalLANtothespecificneedsofindustryanalysistodeterminetheenterprisenetworktopology，thedesignprinciplesofintegratedwiring，Center，roomplanninganddesign，selectionofnetworkequipment.FromallaspectsofbuildingenterpriseLANplanningprogram，withaviewtobuildingontheenterpriseLANtocontribute．KeyWords：EnterpriseLAN；EnterpriseTopology；NetworkEquipmentSelection；LAN毕业设计（论文）报告纸iii目录摘要..........................................................................iAbstract.....................................................................ii第一章绪论...................................................................11.1课题背景...............................................................11.2企业局域网建设的目标和意义.............................................11.3企业局域网建设的整体思路...............................................21.4国内外企业局域网发展现状...............................................2第二章需求分析及项目规划.....................................................42.1项目背景...............................................................42.2企业局域网的要求.......................................................52.2.1设计目标..........................................................52.2.2设计要求.........................................................52.3项目分析...............................................................62.3.1拓扑结构需求分析.................................................62.3.2数据传输需求分析..................................................62.3.3发展需求分析......................................................62.3.4性能需求分析......................................................62.3.5地理布局分析.....................................................72.3.6总投资分析........................................................7第三章局域网技术现状分析与分类...............................................83.1局域网技术定义.........................................................83.2局域网的类型...........................................................83.3局域网的发展趋势......................................................10第四章企业局域网的规划设计..................................................114.1网络拓扑的设计........................................................114.2企业网络的一般结构...................................................124.3企业局域网的带宽需求..................................................13毕业设计（论文）报告纸iv4.4企业综合布线设计原则..................................................134.5网络中心机房规划与设计................................................144.6网络设备的选型........................................................154.7网络操作系统与应用软件的选型..........................................164.8网络可靠性安全性设计和容错............................................174.9无线补充网络..........................................................18第五章网络详细设计..........................................................195.1网络流量分析计算......................................................195.2详细配置..............................................................195.3设备选型..............................................................205.3.1网络核心层的设计与设备选型.......................................205.3.2网络汇聚层的设计与设备选型......................................215.3.3网络接入层的设计与设备选型.......................................225.4企业虚拟局域网典型配置................................................225.4.1设置VTPDOMAIN..................................................235.4.2配置中继.........................................................245.4.3创建VLAN........................................................255.4.4将交换机端口划入VLAN............................................255.4.5IP地址分配.....................................................26第六章总结与展望............................................................28参考文献.....................................................................29致谢.........................................................................30毕业设计（论文）报告纸1第一章绪论1.1课题背景随着计算机信息产
