Claim 4:
5. The method as claimed in claim 2, wherein the statistical information further comprises queue depth change information and priority flow control (PFC) back pressure information, and the determining the ECN threshold based on the packet transmission rate and a target delay comprises:
determining a first ECN threshold based on the packet transmission rate and the target delay;
determining a second ECN threshold based on the queue depth change information;
determining a third ECN threshold based on the PFC back pressure information; and
determining a maximum ECN threshold of the first ECN threshold, the second ECN threshold, and the third ECN threshold as the ECN threshold, wherein the ECN threshold is determined based on the packet transmission rate and the target delay, or the ECN threshold is a maximum ECN threshold supported by a forwarding chip on which the target egress queue is located.
