Analysis Of The Feasibility Of IPTV Businessin EPON

As the development of internet technology over the years, the traditional and simple data services can not meet the user's growing business needs, but also for operators, there is no new economic growth point. In order to meet a wide range of business needs of customers, while providing operators with greater economic benefits, with the streaming media technology, Internet network technology and network bandwidth continues to improve, people are beginning to pay attention to use IP protocol provides a kind of service similar with television (TV) business for consumers. So IPTV service as a new growth point for the business came into being.IPTV (Internet Protocol Television), the Interactive Network TV, which combines Internet, multimedia, communications and other technologies. IPTV can provids digital television and a variety of interactive services for new technologies for home users.It can put forward video programs based on individual needs and then the video server (which already stored large amounts of compressed video programs) can sends the demand programs to users. But traditional access networks, such as xDSL technologies in terms of bandwidth, or QoS, as well as in support of multicast technology is already unable to better meet the needs of business, so it is necessary to find new technologies and networks to carry IPTV business.EPON network and system based on IP technology have the same packaging format as Ethenet network, the data packets can be directly sent into the IP core network and metropolitan area network. Because EPON network has higher bandwidth up to 1Gbit, perfect QoS, and which can support nomal multicast and controllable multicast technology better than others. And because the network using PON technology, which include a large mount of optical fiber and passive devices in the line part,so the the stability and reliability of the equipment is greatly improved, while greatly reduced the cost of routine maintenance.So EPON technology is a good choice for carring the IPTV service in the access network. This article describes the development status of IPTV, its key technologies, and EPON networks and its key technologies. The article focuses on a comparison between traditional access technologies and EPON, its perfect QoS technology and support for multicast and implementation.
