Data transmission method and device, computer equipment and storage medium

The invention provides a data transmission method and device, computer equipment and a storage medium, the data transmission method is applied to a network boundary switch of a user network segment, and the method comprises the following steps: in response to receiving a target data packet sent by a user side, identifying first coding information of a source address and second coding information of a destination address in the target data packet; the first coding information and the second coding information are set based on the service type; configuring a priority label for the target data packet according to the first coding information and the second coding information; and sending the target data packet with the priority label to the convergence network, so that the convergence network sets the priority of the target data packet in the transmission queue according to the priority label of the target data packet, and performs data transmission on the target data packet according to the priority.
