成都理工大学工程技术学院毕业论文企业网远程接入技术的实现作者姓名：专业名称：计算机通信指导教师：企业网远程接入技术的实现摘要作为企业网络平台的一种有效的延伸，远程访问接人技术一直在网络应用中扮演着非常重要的角色。它克服了局域网络技术在覆盖范围和接人形式上的局限性，使网络用户在局域网络范围之外也能够方便地随时访问企业的网络平台。本文是对某IT企业的一个企业网络规划设计的解决方案，文章首先分析了企业网络的设计需求，根据需求提出了设计原则与设计目标，制定了总体的规划设计方案，然后再分层次具体地对该企业的局域网和广域网进行设计，在该方案中，我们采用了VLAN、三层交换、千兆交换、光纤接入、VPN等先进网络技术，基本满足了该企业的需求，并留有足够的扩充空间，以适应今后发展。关键词：企业网络规划设计远程接入VPN-I企业网远程接入技术的实现AbstractAsenterprisenetworkplatformofakindofeffectiveextensions,remoteaccesspickuppersonhasbeeninthenetworkapplicationstechnologyplaysaveryimportantrole.Itovercomethelocalareanetworktechnologyincoverageandpickuppersonintheformofthelimitations,andmakethenetworkusersinthelocalareanetworkoutsidethescopeofalsoisconvenienttoaccessenterprisenetworkplatformatanytime.ThisthesisisadesignprojectforsolutiontothenetinoneITenterprise.First,itanalyzestheneedsofdesignfortheenterpriseaccordingtowhichitputsforwardthedesignprincipleandaimandformulatestheschemeofthewholedesignproject.Secondly,itdesignstheinternetparticularlyindifferentaspects.Inthisscheme,itusesadvancetechnologyofinternet,forinstance,VLAN,exchangeofthreelayers,thousand-trillionswitching,opticalfiberreceiving,VPNandsoon,tobasicallymeettheneedsoftheenterpriseandsaveenoughroomforexpandingtoadapttothedevelopmenthenceforward.Keywords:enterprisenetwork,RemoteAccess,VPN-II企业网远程接入技术的实现目录摘要..........................................................................................................IAbstract...................................................................................................II目录.......................................................................................................III前言.........................................................................................................51企业网远程接入技术..........................................................................61.1根据实际分析企业网....................................................................61.2企业要求实现的技术....................................................................62网络总体规划......................................................................................82.1企业网络设计要领........................................................................82.2VPN技术的实现...........................................................................92.3配置VPN服务器........................................................................103网络具体规划与设计........................................................................123.1网络拓扑图..................................................................................123.2IP地址的规划.............................................................................143.3基于VLSM的子网划分.............................................................163.4在VPN服务器的外网卡上添加相关协议................................173.5三层交换技术与链路聚合的应用..............................................183.6INTERNET接入及地址转换........................
