This application discloses a network congestion control method, apparatus, device, and system, and a storage medium. In an example method, a first switch receives a target signaling packet that is sent by a second switch in a case in which a network congestion status is a target network congestion status. The target signaling packet carries flow source information. The first switch sends, based on the target signaling packet, target flow control information to a network device corresponding to the flow source information. The target flow control information is used to indicate flow control.

Network congestion control method, apparatus, device, and system, and storage medium

This application describes a congestion control method and apparatus. In this application, a network device obtains time information of one or more congestion packets in a sent first data stream, where the one or more congestion packet carries a flag indicating a congestion notification. When the first data stream is congested, the network device obtains a first congestion notification packet based on the time information of the one or more congestion packets in the first data stream, where the first congestion notification packet notifies that a packet is congested beyond a first specified interval. The network device then sends the first congestion notification packet. According to the solutions in this application, a rate of a data stream can be prevented from being increased when the data stream is congested, and packet transmission efficiency is improved.

Congestion control method and apparatus

This application provides a flow rate control method and apparatus. The flow rate control method in this application includes: receiving N explicit congestion notification packets CNPs from a first device, where the N CNPs correspond to a first data flow, and N is a natural number; and sending M CNPs to a second device based on the N CNPs, where the M CNPs correspond to the first data flow, and M is an integer greater than N. This application resolves a problem that rate increase processing is still performed on a data flow when the data flow is congested.
