Network data packet transmission method and device, and storage medium

The invention discloses a network data packet transmission method and device, and a storage medium. The method comprises the following steps: determining that an obtained network data packet is a non-initial data packet corresponding to an established session; deleting a target field in the non-initial data packet for the non-initial data packet based on a pre-stored corresponding relationship between the established session and the target field of the network data packet; and sending the non-initial data packet after the target field is deleted to the second network device based on the established session. According to the embodiment of the invention, optimized transmission processing can be carried out on the non-initial data packet corresponding to the established session according to the pre-stored corresponding relationship between the established session and the target field of the network data packet, so that transmission resources consumed by transmission of the network data packet can be saved, and t
