Claim 3:
4. The method according to claim 1, wherein based on the network performance indicator comprising a quantity of explicit congestion notification (ECN) marking packets transmitted by the leaf node in a previous period, the target control information comprises a target ECN marking parameter, which is used to reflect a slope by which an ECN marking probability varies with a packet queue length, the ECN marking probability is a probability that an ECN marking is made on a transmission packet in a packet queue of the leaf node, and the packet queue length is a length of the packet queue of the leaf node; and
the performing network congestion control on the at least one leaf node based on the target control information comprises:
obtaining, by the at least one leaf node through calculation based on the target ECN marking parameter and a length of a packet queue of each of the at least one leaf node, a target ECN marking probability corresponding to the at least one leaf node; and
making, by the at least one leaf node, an ECN marking on the transmission packet in the packet queue of the at least one leaf node based on the corresponding target ECN marking probability, to notify a source node that communicates with the leaf node to reduce a packet transmission rate or stop packet transmission.
