Abstract: A congestion control method is provided. The method includes obtaining a first traffic characteristic, where the first traffic characteristic includes statistical information generated when a first device forwards traffic in a first period based on a first congestion control parameter, and the first congestion control parameter is obtained according to a first congestion control rule, obtaining a first reward value based on the first traffic characteristic, modifying the first congestion control parameter by using a first step, to obtain a second congestion control parameter, obtaining a second traffic characteristic, where the second traffic characteristic includes statistical information generated when the first device forwards traffic in a second period based on the second congestion control parameter, obtaining a second reward value based on the second traffic characteristic, and performing corresponding processing if the second reward value is greater than the first reward value.

Abstract: This application relates to the field of communications technologies, and discloses a network parameter (for example, an ECN threshold) configuration method and an apparatus, to dynamically configure a network parameter based on a change of a network transmission characteristic, so that the network parameter is dynamically adapted to a change of network traffic, thereby ensuring network transmission performance. The method includes: obtaining network statistical data corresponding to a first period, where the network statistical data includes a network transmission characteristic of a network device in the first period and a first value corresponding to a specified network parameter; determining, based on the network statistical data, a second value corresponding to the specified network parameter; and configuring the specified network parameter of the network device in a second period to the second value, where the second period is a period after the first period.

Abstract: This application discloses a congestion control method and related apparatus. In the congestion control method, a network device first obtains statistical information of a target egress queue within a first time period, where the target egress queue is any target egress queue in the network device. The network device determines an explicit congestion notification (ECN) threshold for the target egress queue within a second time period based on the statistical information of the target egress queue within the first time period, where the second time period is chronologically subsequent to the first time period. When a queue depth of the target egress queue exceeds the ECN threshold within the second time period, the network device sets an ECN mark for a data packet in the target egress queue.

Abstract: A method, an apparatus, and a system for locating a root cause of a network anomaly in the field of network technologies comprises, when a PFC deadlock occurs in a first egress port queue in a network device, the network device determines an abnormal data flow in the first egress port queue based on an access control list, where both an egress port and an ingress port of the abnormal data flow are uplink ports of the network device. The first egress port queue is any egress port queue in the network device. The network device sends anomaly information to a network management device, where the anomaly information includes an identifier of the abnormal data flow. The network management device transmits the identifier of the abnormal data flow to a display device for display by the display device.
