Background
A video conference system includes a Multipoint Control Unit (MCU) and various participating devices such as a video conference server and a terminal. The terminal collects image and sound and sends the image and sound to the MCU through coding. And the MCU fuses or does not fuse the images sent by the terminals according to the conference requirement and then sends the fused images to each participating terminal. Therefore, the audio and video conversation of the multi-party participants is realized. The video conference system server is often a cluster stacking system, and may be composed of a plurality of signaling nodes and a plurality of media nodes. Each media node is configured with a media codec processor and a network transmission device with different capabilities. In a large conference, a plurality of distributed media nodes are generally set to support one conference at the same time, and at this time, the load balancing of media resources is complicated.
The existing media resource load balancing scheme generally uses a media node resource pool to assign a capability value to each media node, and the capability value generally represents the coding and decoding processing capability of the media node. And when a new conference is added, selecting a media node with the maximum idle capacity value for starting the conference.
In a cross-node large-scale conference scenario, in addition to the codec capability of the media node, the network transmission capability of the media node is also considered. When multiple conferences are dispatched in a balanced manner purely from the dimension of the encoding and decoding capacity, the conference effect may be poor due to insufficient network bandwidth of part of terminals, or, because the network transmission capacity is not considered, the situation that the encoding and decoding capacity of part of media nodes is full but the network transmission capacity is empty may occur, and the network transmission resources of the media nodes cannot be fully utilized.
In the related art, no effective solution exists at present for the problems that the conference effect is poor and the media server resources cannot be fully utilized due to the fact that the encoding and decoding capabilities of media nodes and the network transmission capability in a video conference scene cannot be simultaneously balanced and scheduled.

a second determining module, configured to determine a second target media node according to a network transmission capability remaining value of the media node, where the network transmission capability remaining value indicates a number of terminals that the media node can currently access;
and a sending module, configured to send channel information of the second target media node to the terminal, where the channel information is used to instruct the terminal to access the video conference through the second target media node.
8. The apparatus of claim 1,
the first determining module includes:
a determining unit, configured to determine a media node with a largest residual value of media coding and decoding capabilities in the media service cluster as the first target media node;
the starting module comprises:
a starting unit, configured to start the video conference by using the first target media node when the remaining value of the media encoding and decoding capability of the first target media node is greater than or equal to the value of the media encoding and decoding capability required by the video conference.
9. A computer-readable storage medium, in which a computer program is stored, wherein the computer program is configured to carry out the method of any one of claims 1 to 6 when executed.
