Bandwidth allocation method and device, equipment and storage medium

The embodiment of the invention provides a bandwidth allocation method and device, equipment and a storage medium. The method comprises the following steps: determining target estimated bandwidths corresponding to multiple paths of video streams; determining a state degradation sequence corresponding to the plurality of video streams based on the stream attribute information of each video stream, the state degradation sequence comprising a plurality of resolution states arranged in sequence according to a degradation sequence, and each resolution state comprising a transmission resolution at which each video stream is located; based on the state degradation sequence corresponding to the multiple paths of video streams, the current sending resolution of each path of video stream and the target estimation bandwidth, bandwidth allocation processing of resolution degradation is carried out, and target resolution states corresponding to the multiple paths of video streams are determined; and sending the multi-chan
