Abstract: The technology of this application relates to an acknowledgement packet processing method, a communications apparatus, and a storage medium, to reduce an ACK sending frequency and improve data transmission efficiency. The acknowledgement packet processing method is applied to a first communications apparatus, and the method includes generating a first ACK packet based on an acknowledgement ACK mechanism supported by the first communications apparatus, where the ACK mechanism is used to indicate N ACK types corresponding to N ACK packets, a trigger condition required for sending each of the N ACK packets, and feedback information carried in each of the N ACK packets, the first ACK packet is one of the N ACK packets, and N is a positive integer greater than or equal to 2. The method further includes sending the first ACK packet to a second communications apparatus.

Abstract: A link detection technology. In a link detection method, when a target event occurs on paths, in a plurality of paths, whose quantity exceeds a preset quantity, whether the paths on which the target event occurs share a bottleneck link is detected, and congestion control is performed. It can be learned that in the technical solution provided in the embodiments of this application, the target event is a trigger, and shared bottleneck detection is performed after the quantity of the paths on which the target event occurs exceeds the preset quantity. This implements purposeful link detection, reduces system overheads, and brings a fast convergence speed.

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.
