Abstract: 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.

Abstract: This application provides a method and an apparatus for determining a port orientation. The method includes: A first network device receives, through a first port, a protocol data unit PDU sent by a second network device. The first network device determines, based on the PDU, that the first port is an upstream port or a downstream port. In this embodiment of this application, the first network device may determine, based on the PDU sent by the second network device, whether the first port is the upstream port or the downstream port, to provide a basis for subsequently helping an SDN controller reduce load.

Abstract: A flow control method includes: when congestion is detected, determining, by a first switching device, a key flow from a plurality of data flows; generating a back pressure message including a flow attribute value of the key flow; sending the back pressure message to an upstream device of the key flow; and pausing, by the upstream device of the key flow, sending of the key flow, where the back pressure message has no impact on sending of another data flow other than the key flow by the upstream device of the key flow. The present disclosure further provides a switching device that can implement the flow control method.
