毕业设计（论文）基于gmpls智能光网络的流量工程

基于GMPLS的智能全光网络流量工程1本科生毕业设计(论文)题目：基于GMPLS智能光网络的流量工程教学单位_电气信息工程学院__摘要自动交换光网络（ASON）是一种能够自动完成网络连接的新型网络。它由控制面、传送面和管理面三个平面组成，控制面技术是其核心，利用控制面它能够实施动态交换。GMPLS（通用多协议标签交换）是IETF提出的可用于光层的一种通用多协议标签交换技术，由MPLS（多协议标签交换）扩展而来，经历了一个从自动传送光网络（ASTN）发展到ASON，并进而结合了GMPLS的发展过程；GMPLS（通用多协议标签交换)是MPLS技术向光网络发展的产物。它有效地实现了IP和WDM光网络的无缝结合；当前互连网业务量增长迅猛，未来的骨干网必须处理巨大的IP数据流量和实时数据流量，巨大业务流量要求提高网络资源利用率，实时数据流量要求确定的服务质量。为此，未来网络的结构和技术需要新的解决方案。本文论述流量工程对新一代网络的重要性，并且讨论用GMPLS解决流量工程问题的途径。基于GMPLS的智能全光网络流量工程2关键词：ASONOXCLSPLMPGMPLSTEAbstractAutomaticSwitchedOpticalNetwork(ASON)isacompletenetworkcanautomaticallylinkthenewnetwork.Itconsistsofcontrolsurfaces,transmissionandmanagementface-3plane,controlsurfacetechnologyisthecore,usecontrolsurfacesitcanimplementdynamicexchange.GMPLS(GeneralizedMulti-protocolLabelSwitching)issupposedtobeusedfortheopticallayerofacommonmulti-protocollabelpayfortechnology,MPLS(Multi-protocolLabelSwitching)fromtheexpansion.experiencedanautomatictransmissionfromtheOpticalNetwork(ASTN)toASON.proceedwiththedevelopmentprocessGMPLS;GMPLS(GeneralizedMulti-protocolLabelSwitching)isMPLStothedevelopmentofopticalnetworkproducts.technologyIteffectivelyachievetheIPandWDMnetworkseamlessintegration;ThecurrentInternetbusinessgrewrapidly.thefuturebackbonenetworktotheIPaddresstheenormousflowofdataandreal-timedataflow,Trafficdemandstremendousincreaseutilizationofnetworkresources,real-timeflowofdatarequiredtodeterminethequalityofservices.Therefore,thefuturenetworkstructureandtheneedfornew基于GMPLS的智能全光网络流量工程3technologysolutions.Thispaperdiscussestrafficengineeringforthenewgenerationoftheimportanceofnetworks,andtodiscusssolutionswithGMPLStrafficengineeringproblem.Keywords:ASONOXCLSPLMPGMPLSTE目录摘要..................................................................................................................................................1Abstract...........................................................................................................................................2目录..................................................................................................................................................31引言..............................................................................................................................................51.1MPLS工作原理..............................................................................................................51.1.1路由和交换概念...................................................................错误!未定义书签。1.1.2标志交换转发部件...............................................................错误!未定义书签。1.1.3标志交换路由器(LSR).........................................................错误!未定义书签。1.1.4MPLS工作原理......................................................................错误!未定义书签。1.2GMPLS与MPLS对比......................................................................................................51.3IPoverWDMwithGMPLS关键.............................................................................71.4新一代网络网络流量现状...........................................................................................81.5各章节安排...................................................................................................................92GMPLS技术................................................................................................................................102.1GMPLS工作原理..............................................................................................................102.2GMPLS在ASON控制平台应用........................................................................................122.2.1控制平面功能.....................................................................................................122.2.2控制平面服务...................................................................................................122.2.3控制平面协议...................................................................................................13基于GMPLS的智能全光网络流量工程42.2.4信令协议...........................................................................................................132.2.5路由协议的流量工程扩展...............................................................................142.2.6链路管理协议.................................................................................................142.3小结...............................................................................................错误!未定义书签。3全光网络...................................................................................................................................153.1全光网的功能与结构.....................................................................................................153.1.1网络结构元件.......................................................................................................153.1.2分层分割...............................................................................................................153.1.3拓扑结构...............................................................................................................153.2全光交换...................................
