摘要: A system and method of integrating IP multicasting with application layer multicasting for media streaming. The proposed approach teaches forming an overlay P2P tree using a scalable protocol. New node either detects an existing IP multicasting island to join or forms a new one. Ingress node of each island is adaptively elected and streams media to nodes in its island via IP multicasting, while getting the media from its parent node via traditional unicast to achieve much lower end-to-end delay and link stress.
