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 network device adds a fixed value to a congestion threshold (CT) when a first period ends. Detects whether a difference obtained by subtracting average traffic load of a queue in the first period from average traffic load of the queue in a second period is greater than a target increase value, sets the CT based on a detection result when the second period ends, where the first period is previous to the second period; marks a received packet when a quantity of packets buffered in the queue is greater than the CT, enqueues the marked packet and sends the marked packet to a receiving device.

Abstract: A network congestion control method includes, during transmission of a first service flow, a first network device that obtains a measurement packet including groups of measurement results corresponding to the first service flow, and each group includes an identifier of a forwarding device on a forwarding path of the first service flow and a measurement value corresponding to the forwarding device. The first network device determines, based on the groups, a congested second network device on the forwarding path. The first network device determines a control policy based on location information of the second network device, where the control policy resolves congestion of the first service flow.
