This application provides a flow control method, including: sending, by a first device, a first data packet to a second device in a first sending mode; determining, by the first device, a network congestion status; and sending, by the first device, a second data packet to the second device in the second sending mode, where the second sending mode is a sending mode determined by the first device based on the network congestion status, and the second data packet is a data packet to be sent after the first data packet.

Flow control method and apparatus

Embodiments of this application provide a method, includes: receiving a first data flow that includes a plurality of data units; inputting Ndata units of the plurality of data units and a first source marking unit into the first source queue; inputting Mdata units of the plurality of data units and a first target marking unit into the first target queue, wherein the Ndata units and the Mdata units are different data units; scheduling the Ndata units and the first source marking unit based on the first source marking unit and the first target marking unit; and scheduling the first target marking unit and the Mdata units, wherein the first target marking unit and the Mdata units are scheduled later than the Ndata units and the first source marking unit are scheduled.

Data scheduling method and switching device

Embodiments of the invention disclose a data transmission method, a device, and a computer storage medium to perform data transmission. A congestion status of a transmission port is obtained by a first device. The transmission port is a communications port used by the first device when a second device transmits data to the first device. The congestion status is used to indicate whether data congestion occurs on the transmission port. Indication information is sent to the second device when a mode switching condition is met. The indication information is used to instruct the second device to switch a transmission mode used when the second device transmits the data, so that the second device transmits the data to the first device in a switched transmission mode, and the mode switching condition is associated with the congestion status of the transmission port.

Data transmission method, device, and computer storage medium

The present disclosure relates to congestion flow identification methods. One example method includes obtaining, by a network device, a queue length of a non-congestion flow queue, where the non-congestion flow queue includes a data packet or description information of the data packet, determining, by the network device, a target output port of a target data packet when the length of the non-congestion flow queue is greater than or equal to a first threshold, where the target data packet is a data packet waiting to enter the non-congestion flow queue or a next data packet waiting to be output from the non-congestion flow queue, and when utilization of the target output port is greater than or equal to a second threshold, determining, by the network device, that a flow corresponding to the target data packet is a congestion flow.
