The Design And Implemention Of IPTV Service In Experimental Converged Network

Three nets fusion refers to the integration of telecommunications networks,radio and television network and Internet, it is not just the network mergingin the physics, more important is to realize integration of high-level servicesand applications.It means that the network could provide users voice, data, image and other business at the same time. In recent years,these applications and services, especially the typical services of IPTV are widely used, the related professional talent demand is increasing.Therefore, the construction of a practical convergence experiment network,and in the implementation of IPTV business which, is very practical. Students could use this network to experiment, and the enterprise staff could have trainings here.It kills two birds with one stone.In this paper, relying on Sichuan Post and Telecommunication College three nets fusion experimental network construction project, aim at the design and implementation of IPTV service in the network convergence, the writer in-depth analysis based on the IPTV system. In order to realize the practical operation network simulation network architecture, equipment types and functions be identical with the actual operation of the network, the capacity of the network be enough and can realize the smooth expansion of the actual demand, the IPTV system design, hardware selection, configuration and debugging to do had be in-depth and comprehensive researched, formed a complete integration design scheme of IPTV system in the network, and realized the IPTV service in the network. The main contents of this thesis include:1.On the base of analyzing the overall structure of the three nets fusion experimental network, in-depth analysed of the general requirements of IPTV system, designed the IPTV experiment in the network architecture.2.According to the actual needs of the construction of experimental network, expounds the specific design scheme and realization method of the front-end system experiment in the network.3.A detailed analysis of the design and realization of broadband access network in IPTV transmission system, according to the IPTV’s demand for bandwidth, as well as the development of the current access technology, choose EPON and GPON as access technology experiment in the network, describes the structure design, access network equipment selection and configuration and debugging.4.Discusses the design and implementation of IPTV terminal system, expounds the configuration process and method of the experimental network of various types of terminals.5. The whole debugging method of IPTV business, the business of IPTV experimental network test.
