1. A congestion control method, comprising:
generating, by a sending device, a to-be-sent unscheduled data packet of a first flow; upon determining, based on an unscheduled packet send window shared by all flows, that the to-be-sent unscheduled data packet meets a sending condition, determining whether to request to add a quota for the unscheduled packet send window and/or a scheduled packet send window corresponding to the first flow, wherein determination of whether a scheduled data packet of the first flow meets the sending condition is based on the scheduled packet send window corresponding to the first flow; and
upon determining that the quota needs to be requested to be added for the unscheduled packet send window and/or the scheduled packet send window corresponding to the first flow, setting indication information in the to-be-sent unscheduled data packet, and sending, to a receiving device, the to-be-sent unscheduled data packet in which the indication information is set, wherein the indication information indicates the receiving device to send a signaling packet, to trigger the sending device to add the quota for the unscheduled packet send window and/or the scheduled packet send window corresponding to the first flow.
