APPLICATION-LEVEL ROUTING PROTOCOL FOR MULTIPARTY AUDIO-VIDEO CONFERENCING

摘要

multipoint audio-video conferencing applications for System-level routing protocol to implement (114) and method ( 500) is described. In one embodiment, the application-level per-stream (per-stream) routing technology (202) controls the audio data and video data between the host conference members in the network independently. Different audio application-level multicast (ALM) tree 220 is generated by the respective members, the shortest path of the data transmission-path-first is updated dynamically according to the selection (232), the other members of the video conference is used to send audio data. Similarly, different video ALM tree 218 is generated by each of the members, the largest of the data transmission path-path-first is dynamically updated based on the selection (228), the video data to other members of the video conference The send is used. Each can take advantage of IP Multicast (222) in the segment of independent audio and video IP multicast-enabled network ALM tree for the members.
