Data transmission method and device, equipment and storage medium

The invention discloses a data transmission method, apparatus and device, and a storage medium. The method comprises the steps of determining a bandwidth required by an input channel for receiving a data packet sent by a network switch and a transmission rate of the data packet; determining an idle bandwidth of a preset output channel based on a preset bandwidth allocation mechanism; and allocating the idle bandwidth to the input channel based on the required bandwidth and the transmission rate, so as to input the data packet into a preset DDR (Double Data Rate) memory based on the input channel, thereby enabling the DDR memory to cache the data packet. In the application, the idle bandwidth of the output channel is allocated to the input channel for receiving the data packet through a bandwidth allocation mechanism, so that the bandwidth required by the input channel is met, retransmission of the data packet is prevented, and the data transmission efficiency is improved. 本申请公开了一种数据的传输方法、装置、设备及存储介质，该方法包括：确定接收
