Embodiment 1
[0043] See figure 1 , the embodiment of the present invention provides a distributed multi-transmission channel network live video parallel distribution method, including:
[0044] S1. Divide the live video stream into multiple sub-slices; wherein, the sub-slices include common sub-slices and key frame sub-slices;
[0045] S2. Push the live video stream to the edge node of the CDN network in units of the sub-slices, and schedule different physical devices RD in the virtual machine to transmit different slice groups;
[0046] Wherein, several physical devices RD are set in the virtual machine, and the physical devices RD are used to gather uplink and downlink surplus bandwidth; the slice grouping is obtained by grouping the sub-slices; each slice grouping forms a substream;
[0047] Select RD packets according to the number of pre-configured subflows inside the same virtual machine, and the physical device RD selects and distributes subflows corresponding to the RD packets; ...
