Abstract: 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.

Abstract: The present disclosure relates to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node performs PFC detection on a first port queue of a first port, and determines that a first preset condition is met. The first preset condition includes: detection is performed in N consecutive first time segments, when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold. The first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer.
