摘要作为企业网络平台的一种有效的延伸，远程访问接入技术一直在我们的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入形式上的局限性，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。顾名思义，远程访问技术首先解决的问题就是地域的局限。用户不再需要处于企业局域网络平台覆盖范围之内，通过局域网接入方式来访问企业网络应用服务。此外，远程访问技术解决的另一个问题是灵活性，不论用户身在何处——在家中，或在另一个城市出差，都能够利用远程访问技术接入到企业内部网络平台。本文是对一企业网络所做的设计规划方案，本文首先分析了企业远程技术的应用于前景提出的背景和VPN技术的实现。在用Dynamips软件PacketTracer5等软件进行局域网于广域网的设计连接配置。以满足当今企业网的需求和发展。关键字企业网VPN远程接入AbstractAsaneffectiveenterprisenetworkingplatformextension,remoteaccess,accesstotechnologyhasbeenappliedinournetworkplayaveryimportantrole.Itovercomesthelocalareanetworktechnologyintheformofcoverageandaccesslimitations,sothatusersoutsidethelocalareanetworkcaneasilyaccessthecorporatenetworkplatformatanytime.Asthenamesuggests,remoteaccesstechnologytosolvethefirstproblemisthatgeographicallimitations.Usersnolongerneedinacorporatelocalareanetworkplatformwithinthescopeofcoverage,throughtheLANaccessmethodstoaccessthecorporatenetworkapplications.Inaddition,theremoteaccesstechnologytosolveanotherproblemistheflexibility,nomatterwhereyouare-athome,ortravelinginanothercity,areabletouseremoteaccesstechnology,accesstothecorporateinternalnetworkplatform.Thisarticleismadeonacorporatenetworkdesignandplanningprograms,thispaperfirstanalyzesthebusinessoutlookforlong-rangetechnologyusedinthebackgroundandVPNtechnologyimplementation.PacketTracer5usingDynamipssoftware,suchassoftwaredesignoftheLANontheWANconnectionconfiguration.Inordertomeettheneedsoftoday'senterprisenetworksanddevelopment.Keywords:EnterpriseNetwork，VPN，RemoteAccess目录企业网接入技术中文摘要······················································1企业网接入技术英文摘要······················································2目录······································································3企业网远程接入技术...........................1目录..................................3前言.....................................41.需求分析........................................................................................................................5（1）VPN技术提出的背景....................................................................................................5（2）VPN技术的实现............................................................................................................6（3）VPN技术特点................................................................................................................6(4)VPN技术当前需求............................................................................................................82设计内容..........................................................................................................................9(1)Cisco相关软件介绍（dynamips和secureCRTpackettrace5.0）软件的介绍..9(2)准备内容.....................................................................................................
