Abstract

The invention provides a multicast service load sharing method, a multicast service load sharing system and a video live broadcast system. The method comprises the following steps of: respectively setting a first multicast transcoding server, a first convergence point RP, a second multicast transcoding server and a second convergence point RP in two areas; wherein the first RP synchronizes the multicast stream to the second RP, and the first multicast transcoding server and the second multicast transcoding server respectively transcode the multicast stream and respectively send the transcodedmulticast stream to the first RP and the second RP for registration for providing live broadcast service. The invention discloses a method, a system and a video live broadcast system. By setting a networking structure of the double RPs and the multicast transcoding server remotely and carrying out related data configuration, faults of the multicast transcoding server or the RPs can be prevented from influencing users of the whole network, and meanwhile, remote nodes can realize mutual hot standby, so that the effect of remote disaster recovery can be achieved, and the use experience of the users can be improved.

Description

technical field [0001] The invention relates to the field of multicast technology, in particular to a multicast service load sharing method, system and video live broadcast system. Background technique [0002] Live broadcast services can be realized through unicast or multicast. Most domestic IPTV live broadcast services are realized through multicast technology, and multicast rendezvous point RP (Rendezvous Point) needs to be configured. For example, the IPTV platform sets up a multicast transcoding server to register the multicast video stream to the RP, and the terminal (set-top box) pulls the stream to the RP to watch live programs. At present, the IPTV multicast transcoding server (single platform) and RP of domestic operators are basically set up in a single city, which cannot achieve the effect of remote disaster recovery. Once a failure occurs, all users on the entire network will be affected. Contents of the invention [0003] One or more embodiments of the pres...
