【摘要】：IPTV即交互式网络电视,其功能包括传统的直播,还有点播,回看,时移等诸多新媒体网络电视功能,能够适应当今网络飞速发展的趋势、充分有效地利用网络资源。目前中国联通集团已将其定位为第二大产业进行大力推广。菏泽联通在发展IPTV业务过程中,出现网络承载流量过大、组网复杂、开通困难、指标过低、故障频发等诸多问题,亟待解决。本文希望通过深入研究IPTV设备组网和工单流程,发现问题原因,找寻解决办法。笔者不仅参与了前期为IPTV业务上线而打下基础的电子工单系统建设、OLT解耦升级、HGU新业务开通等工程,而且全程参与了菏泽联通IPTV业务的组网规划设计、建设,工单流程测试和上线,以及与之相匹配的设备升级等工作,包括城域网和接入网层面的IPTV数据配置、OLT上联板扩展10G、NE5000E设备更换等项目。本文来源于自参加工作至今笔者在联通企业中的亲身经历和调查研究。本文的选题就是以这些项目以及积累的大量信息和经验为基础,对IPTV业务在菏泽联通的应用与发展进行讨论和分析。本文首先对菏泽联通开展IPTV业务的网络背景和业务背景进行了简要介绍,包括城域网现状以及从单播改为组播的原因;其次详细描述了中兴和华为IPTV系统组网和业务流程,并对两者在菏泽联通的部署进行了绘图说明;最后重点描述了菏泽联通IPTV业务开通方法、相关指标、故障案例及处理方法,着重讨论了这些因素对IPTV发展的利害,为避免IPTV开通过程出现问题提供经验,为菏泽联通下一步推动IPTV发展提供借鉴。
[Abstract]:IPTV is interactive network television, its function includes traditional live broadcast, as well as many new media network TV functions, such as on demand, looking back, time shift and so on, which can adapt to the trend of the rapid development of network nowadays and make full and effective use of network resources. At present, China Unicom Group has positioned itself as the second industry to vigorously promote. In the process of developing IPTV service, Heze Unicom has many problems, such as too large network carrying flow, complex network construction, difficult opening, too low index, frequent fault and so on, which need to be solved urgently. This paper hopes to find out the cause of the problem and find out the solution by deeply studying the IPTV equipment networking and work order flow. The author not only participated in the construction of electronic worksheet system, OLT decoupling upgrade, HGU new service opening and so on, but also participated in the network planning, design and construction of Heze Unicom IPTV service. The testing and commissioning of the worksheet process, as well as the corresponding equipment upgrades, include IPTV data configuration at the metropolitan area network and access network level, and the extension of 10GN NE5000E equipment replacement projects on the OLT. This paper comes from the personal experience and investigation of the author in China Unicom. Based on these projects and accumulated information and experience, this paper discusses and analyzes the application and development of IPTV service in Heze Unicom. Firstly, this paper briefly introduces the network background and service background of IPTV service in Heze Unicom, including the current situation of man and the reason of changing from unicast to multicast. Secondly, the network and business process of ZTE and Huawei IPTV system are described in detail, and the deployment of them in Heze Unicom is illustrated. In the end, the paper describes emphatically the opening method, related indexes, failure cases and handling methods of IPTV service of Heze Unicom, and emphatically discusses the benefits of these factors to the development of IPTV, and provides experience for avoiding the problems in the process of IPTV opening. Heze Unicom for the next step to promote the development of IPTV to provide reference.
