Packet loss processing method, apparatus, device, medium and product

Abstract

The application relates to the technical field of communication, and provides a packet loss processing method, device, equipment, medium and product. The method comprises the following steps: obtaining a total sequence number of a to-be-sent data packet, determining a container identifier and a container internal sequence number according to the total sequence number, and encapsulating the container identifier, the container internal sequence number and a path switching identifier for the to-be-sent data packet to obtain a first data packet; and sending the first data packet, so that a network switching device forwards the first data packet to a receiving end device based on the container identifier and the path switching identifier. The container identifier and the container internal sequence number are uniquely determined by the total sequence number, thereby establishing a constant identity mapping for each data packet, which can be used for accurate retransmission of the corresponding data packet; the existence of the path switching identifier enables the sending end to continuously use the original packet loss determination rule without the need of re-computing or maintaining a dynamic mapping table, thereby reducing retransmission delay and computation cost and ensuring the consistency of packet loss determination logic before and after path switching and the accuracy of retransmission.
