【摘要】：随着互联网技术的提高和宽带用户的普及,固网运营商提供的宽带业务已经发展到基本饱和状态。面对这种市场现状,必须发现和创造更多商业机会,寻找新的业务增长点来提升差异化竞争,突破终端瓶颈,培养已有用户的忠诚度,降低客户流失率。这时IPTV业务应运而生,充分有效的利用现有网络资源,扩展了互联网业务的使用终端,更好的适应当今网络飞速发展的趋势,提升了固网运营商的核心竞争力。IPTV利用已有宽带网络的基础设施优势,依托其海量高清的试听内容储备和互联网双向交互的技术优势,为用户提供了更个性化更多选择的新一代电视收视方式,无论在在内容和形式等方面都超过传统电视,使用户得到更灵活更体贴的服务。PTV也为电信运营商启动了潜在的新业务新收入的机遇,业务融合是网络发展的趋势,IPTV业务的开展是促使三网融合的契机,前景非常乐观。2012年起,B市联通开始投入IPTV业务的建设与试点,作者参与了该市联通IPTV业务的基于IP城域网的网络现状,本课题首先对整体架构和网络容量是否能够满足IPTV业务的开通做了评估和预测,根据IPTV的业务特性,在网络端采取组播技术作为首要关键支撑技术来节省带宽,解决视频流的复制问题。而后给出了IPTV业务承载方案,包括IPTV端到组网方案、STB(Set Top Box,网络机顶盒)的网络接入认证和地址分配方案、组播复制点选择方案等。详细阐述了实现IPTV业务涉及到的几种IP组播协议,制定了IPTV业务组播部署方案。最后通过测试实际验证了方案可以实现预期效果,在几个试点小区实现了IPTV业务。目前,该IPTV试点项目已经在B市正常投入使用,网络运行正常,达到了该项目的预期设计要求。在文章的最后,对该方案进行了总结,并从IPTV长期规模化的发展考虑,提出了B市联通城域网的不足,对下一步的网络优化和改造工作进行了展望。
[Abstract]:With the improvement of Internet technology and the popularity of broadband users, broadband services provided by fixed network operators have developed to a basic saturation state. In the face of this market situation, we must find and create more business opportunities, find new business growth points to enhance differentiated competition, break through terminal bottlenecks, cultivate the loyalty of existing users, and reduce customer turnover. At this time, the IPTV service emerged as the times require, making full and effective use of existing network resources, expanding the terminal of Internet services, and better adapting to the rapid development trend of today's network. Improve the core competitiveness of fixed network operators. IPTV takes advantage of the existing broadband network infrastructure, relying on its massive high-definition audition content storage and two-way Internet interaction technology advantage, Provides users with a more personalized and more selective new generation of TV viewing, both in terms of content and form than traditional television, Making users get more flexible and considerate service. PTV also starts the potential new business revenue opportunities for telecom operators. Service convergence is the trend of network development and IPTV service development is an opportunity to promote the integration of three networks. The prospects are very optimistic. Since 2012, China Unicom has begun to invest in the construction and pilot of IPTV services, and the author has participated in the current situation of IP man based network of IPTV services in the city Unicom. In this paper, we first evaluate and predict whether the whole architecture and network capacity can meet the requirements of IPTV services. According to the characteristics of IPTV services, multicast technology is adopted as the first key supporting technology to save bandwidth at the network end. Solve the problem of video stream replication. Then, the scheme of IPTV service carrying is presented, including the network access authentication and address assignment scheme of IPTV end-to-network scheme (STB-STB (Set Top Box, network set-top box), the scheme of multicast replication point selection and so on. Several IP multicast protocols involved in implementing IPTV services are described in detail, and a multicast deployment scheme for IPTV services is developed. Finally, the test results show that the scheme can achieve the desired results, and the IPTV service is implemented in several pilot communities. At present, the IPTV pilot project has been put into use in B city, and the network is running normally, which meets the expected design requirements of the project. At the end of the paper, the scheme is summarized, and considering the long-term development of IPTV, the shortcomings of the metropolitan area network of Unicom in B city are put forward, and the future work of network optimization and transformation is prospected.
