| Abstract: | With the development of communication network to broadband, convergence and IP technologies, the IPTV application is developed rapidly. Based on the IPTV mulficast technologies of existing network convergence, the differences of IPTV multicast implementation technology are analyzed between fixed network with application layer, BRAS （Broadband Remote Access Server） and DSLAM （DSL Access Multiplexer） and mobile network. The analysis shows that IPv6 multicast technology becomes a high eflficient solution to provide Internet multicast and an important supporting technology of next generation network application, which brings wide application prospect for IPTV. |
