Research And Application Of The Iptv Network Planning And And Security Systems

IPTV is a broadband network to provide users with interactive multimedia services business. Countries vigorously promote the rapid development of triple play applications, IPTV has become a domestic technology hot spots, IPTV as a new technology to change the old TV mode of transmission, because it is broadband-based television, therefore, to the TV true sense of the interaction. IPTV is in a boom phase, through the IPTV platform, provide users with a rich, personalized video programs, as well as many other value-added services, thereby stimulating home broadband access services to enhance, expand customer reach.2011S of IPTV subscribers number has exceeded20000w City, China Unicom is also actively involved in the IPTV test and construction, the author was involved w City Unicom IPTV network planning and deployment optimization, including program development, testing, the source of the paper to the enterprise project. In this paper, the fixed-line communication network of the actual situation and the S-province region, IPTV comprehensive advantages, the development of S-province region of IPTV development plan. IPTV can not only meet the needs of the operators business innovation and changing business ideas for operators to achieve a strategic transformation to provide practical entry point for IPTV means that the new subscriber growth, new business growth and higher ARPU value. For IPTV services, multicast technology is one of the key technologies of IPTV, IP multicast technology to determine the IPTV and effects, and closely related to the telecom operator’s business income. Point of view of from IPTV actual business operations, combined with multicast technology to analyze the technical requirements for IPTV service IP broadband metropolitan area network bandwidth, multicast, QoS, etc. from the point of view, analyze and summarize the advantages of the various implementations shortcomings, developed a program of transformation experiments and implemented, network hosted IPTV service, the success of the system test run, large-scale commercial telecom operators in the future reference and guidance. Completion of the S Provincial IPTV network planning and deployment optimization. The building of the local transmission network planning, network strategy, as well as transmission network carrying in-depth analysis. This paper analyzes the problems of the W local transmission network, aimed at analyzing the IPTV network planning and supporting transmission construction background. Goal of network planning ideas of the local transmission network, the resource requirements of the network strategy, as well as the main bearer service transmission network, the IPTV service that hosts the schema. And local transmission network carrying multicast and QoS deployment norms. Mainly elaborated measures to protect the IPTV broadband indicators.Based on the survey of the existing network, the theoretical analysis. The following results:(1) recent fiber-optic broadband access network will be large-scale construction, the thesis summarize the experience of the construction of the transmission network, the development of follow-up network construction and expansion projects IPTV some guidance.(2) to analyze the local transmission network carrying the introduction of strategies and requirements of the building, especially for multicast and QoS deployment specification related issues are described to strengthen the technical reserves of the transmission network.(3) have some value in the system transmission networks, broadband access network building ideas, recent network integration, network construction and long-term network planning coordinated.(4) to together the current IPTV supporting the actual construction of the initial completion of the S Provincial IPTV network planning and deployment optimization.
