Abstract
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.
