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.

Acknowledgement packet processing method, communications apparatus, and storage medium

A round-trip time (RTT) evaluation system includes sending, by a first device, a plurality of packets to a second device on a path, where each of the packets carries a timestamp indicating a sending time of a corresponding packet, determining, by the second device based on a statistical value of one-way delays (OWDs) of the packets, timestamps carried in the packets, sending, by the second device, an acknowledgements (ACKs) to the first device, where the ACKs include the timestamps and ACK time information, and determining, by the first device, measurement values of an RTT of the path based on the timestamps, the ACK time information, and times when the ACKs are received.
