毕业设计论文-基于通信IPRAN技术的原理和组网.doc

摘 要 当前，伴随着数字化和网络化的飞速发展，数据业务已逐渐成为各运营商网络承载的主体，同时，在移动互联网、物联网、云计算等概念的带动下，数据业务今后的增长势头必将更加迅猛。运营商的传统承载网是基于TDM/SDH方式的语音业务为主，面对带宽需求的迅猛增长已经无能为力。基于TDM/SDH方式进行改良的多业务传送平台MSTP技术，由于只是端口级的IP化，仅适合于3G初、中期的业务和L2专线业务的承载。因此，采用动态IP技术，以路由器为主构建承载网络的IP RAN技术应运而生。 本文就四川省巴中市电信IP RAN的网络建设，首先介绍了IP RAN技术的产生以及原理；其次，就IP RAN网络的组网方案和硬件设备以及各层的路由协议进行了详细阐述；最后，就巴中市电信IP RAN承载网网络建设进行了较为详细的规划设计和部署。 关键词：IP无线接入网；数据业务；承载网；路由协议 Abstract Currently, with the rapid development of digital and network, data service has gradually become the operator carrying the body of the network, at the same time, in the mobile Internet, Internet of things, such as cloud computing concept leads, the growth of data service in the future will be even more rapidly.Operators of traditional ways of bearing network is based on TDM/SDH voice business is given priority to, in the face of the rapid growth of bandwidth requirements have been powerless.Based on TDM/SDH improved more business in the form of MSTP technology transfer platform, because the only port of IP, only suitable for 3 g in the early, middle business and the bearer of the L2 special business.Therefore, by using dynamic IP technology, is given priority to with routers build hosted network IP RAN technology arises at the historic moment. BaZhongShi telecom IP RAN network construction in sichuan province are presented in this paper, firstly the paper introduces the technology of IP RAN and principle;Second, IP RAN network scheme and hardware equipment and network routing protocol of each layer in detail;Finally, just BaZhongShi telecom IP RAN bearing network network construction has carried on the detailed planning and design and deployment. Keywords:IP Radio Access Network; date service; bearer network; routing protocol 目 录 摘 要 I Abstract II 1 绪论 1 1.1 IP RAN技术产生的背景 1 1.2 IP RAN技术的现状与发展趋势 1 1.2.1 现状 1 1.2.2 发展趋势 2 2 IP RAN技术 3 2.1 定义 3 2.2 基本原理 3 2.3 优势 4 2.4 与其它技术的比较 5 2.4.1 与TDM/SDH比较 5 2.4.2 与MSTP比较 5 2.4.3 与PTN比较 6 3 IP RAN网络方案及建设原则 8 3.1 组网方案 8 3.2 建设原则 9 3.2.1 A
