Abstract: This application discloses network congestion control methods and apparatuses. In an implementation, a method comprises: obtaining, by the an intelligent network interface card comprised in a network congestion control apparatus, at least two types of traffic. Identifying, by the intelligent network interface card, algorithm matching features of the at least two types of traffic, and in response to determining to perform congestion control on one type of traffic of the at least two types of traffic, determining, by the intelligent network interface card, a congestion control algorithm that matches an algorithm matching feature of the one type of traffic. Performing, by the intelligent network interface card, congestion control on the one type of traffic according to the congestion control algorithm that matches the algorithm matching feature of the one type of traffic.

Abstract: A congestion control method and an apparatus are disclosed. The method includes: after a sending device generates an unscheduled data packet of a first flow, if it is determined, based on an unscheduled packet send window shared by all flows, that the unscheduled data packet meets a sending condition, determining whether to request to add a quota for at least one of the unscheduled packet send window and a scheduled packet send window corresponding to the first flow; and if it is determined that the quota is requested to be added for the at least one of the unscheduled packet send window and the scheduled packet send window corresponding to the first flow, setting indication information in the unscheduled data packet, and sending, to a receiving device, the unscheduled data packet in which the indication information is set.

Abstract: The present invention discloses a packet control method and a node device, to improve reliability of a data flow in a transmission process. The method includes: After receiving a pause frame, a first node automatically applies, based on adjustment information that is of a send queue of a data flow and that is recorded in a state record set, the pause frame to all queues associated in an adjustment process of the send queue of the data flow. In this way, a packet loss problem in a data transmission process can be avoided without adjusting an XOFF/XON threshold of a receive queue and without increasing a quantity of pause frames in a network system, thereby improving reliability of the data flow in the transmission process.
