Study Group 9
recently approved a Recommendation on IP multicast.
multicast is seen a promising technology for providing IP-based video distribution
because of its bandwidth efficiency while accommodating millions of clients.
J.283 provides a set of architectural concepts for constructing and meeting the
service quality requirement of a stable IP-based video distribution network. It
uses network layer (Layer-3) route diversity between the server edge routers
and the client edge routers.
