Claim 5:
6. The method according to claim 1, wherein based on the network performance indicator comprising a quantity of priority-based flow control (PFC) packets transmitted by the leaf node in a previous period, the target control information comprises a target PFC feedback parameter, which is used to reflect how a PFC notification message sent by the leaf node varies with a length of a 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:
based on the length of the packet queue of the at least one leaf node being greater than or equal to a first parameter threshold in the target PFC feedback parameter, sending, by the at least one leaf node, a first PFC notification message to a source node that communicates with the at least one leaf node, to notify the source node to stop transmitting a priority packet indicated by the first PFC notification message; or
based on the length of the packet queue of the at least one leaf node being less than or equal to a second parameter threshold in the target PFC feedback parameter, sending, by the at least one leaf node, a second PFC notification message to a source node that communicates with the at least one leaf node, to notify the source node to continue transmitting a priority packet indicated by the second PFC notification message.
