PACKET TRANSMISSION METHOD AND APPARATUS, AND DEVICE

Abstract

A packet transmission method includes: obtaining a target rate limitation policy and a target explicit congestion notification (ECN) parameter corresponding to the target port; when transmitting specified-type data in a target priority queue corresponding to the target port to a destination device, adding a congestion mark to the specified-type data based on the target ECN parameter, wherein the congestion mark is configured to allow the destination device to transmit first-class congestion notification packets (CNPs) to a source device; based on the target rate limitation policy, performing rate limitation on the first-class CNPs, and transmitting the first-class CNPs remaining after rate limitation to the source device; determining a target packet rate; and based on the target packet rate, generating second-class CNPs, and transmitting the second-class CNPs to the source device.
