Abstract: including, Acknowledgment information sent by a receive end to a transmit end includes a blacklist, or includes a blacklist and a whitelist. In other words, the receive end notifies, in time each time, the transmit end of information of a plurality of data packets that have not been received. In this way, the transmit end can retransmit the data packets to the receive end in time. The receive end indicates the whitelist to the transmit end, so that the transmit end can learn, in time, of a data packet newly received by the receive end. This avoids a bandwidth waste caused by invalid retransmission. In each round of retransmission, the transmit end retransmits a retransmission packet a plurality of times, and time for retransmission is inconsecutive. This avoids a retransmission failure caused by consecutive packet losses, and improves a retransmission success rate.
