Multicast Architecture Over Next Generation Network

ITU-T SG13 is standardizing multicast framework architecture of next generation network. This specifies the architecture and functions of next generation network multicast services that make use of next generation network architecture and its features. In this paper, the authors describe the functional architecture of next generation network for multicast services in NGN release 2. Efficient multicast data delivery for multimedia applications such as IPTV, video multicast stream and etc., is one of the most challenging issues for multicast services in Next Generation Networks (NGN).
