摘要： This application discloses a congestion control method and an apparatus. In this application, 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, where the indication information indicates the receiving device to send a signaling packet, to trigger the sending device to add the quota for the at least one of the unscheduled packet send window and the scheduled packet send window corresponding to the first flow. According to this application, a network latency can be reduced.

摘要： This application provides a network congestion handling method, a model update method, and a related apparatus. The method includes: obtaining network status information; determining, based on the network status information and an explicit congestion notification ECN optimization model, a reference probability corresponding to recommended ECN configuration information; determining destination ECN configuration information based on the reference probability; and performing ECN marking on a packet by using the destination ECN configuration information. In the foregoing technical solution, the destination ECN configuration information finally used by a network device is applicable to a current operating environment of the network device. This improves operating efficiency of the network device, and improves performance of the network device and user experience.

摘要： A parameter adjustment method (500) and apparatuses (1000, 1100) are provided. The method (500) includes: A first exploration device corresponding to a first service node receives a first parameter set from a management device, where the first parameter set includes one or more parameters used by the first exploration device to perform parameter adjustment, the first service node is any one of a plurality of service nodes included in a data center network, and the plurality of service nodes one-to-one correspond to a plurality of exploration devices. The first exploration device obtains a network status of the first service node based on each parameter adjustment until the network status reaches a preset condition, where each parameter adjustment includes: adjusting one parameter in the first parameter set. The parameter is flexibly adjusted based on the network status, to be applicable to different services. This can improve network performance, and further improve service performance.

摘要： Embodiments of this application disclose a network congestion control method, a node, a system, and a computer storage medium, where the method is applied to a spine-leaf network system. The system includes a spine node and at least one leaf node that communicates with the spine node. The method includes: The spine node receives network information sent by the at least one leaf node, where the network information includes network topology information of the leaf node and a network performance indicator of the leaf node; networks the at least one leaf node and the spine node based on the network topology information of the at least one leaf node, to obtain a combined network topology; and if the combined network topology is a global network topology of the spine-leaf network system, performs network congestion control on the at least one leaf node based on the network performance indicator of the at least one leaf node. This application can resolve a problem that an existing network congestion control solution cannot meet network performance requirements such as a low latency and a high throughput in a control process because network traffic changes dynamically.
