Claim 6:
7. 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 is PFC feedback control information, which is used to indicate whether a source node that communicates with the leaf node is allowed to transmit a priority packet indicated by the PFC feedback control information; and
the performing network congestion control on the at least one leaf node based on the target congestion control information comprises:
based on the PFC feedback control information being used to indicate that transmission of the priority packet indicated by the PFC feedback control information is not allowed, sending, by the at least one leaf node, a first PFC notification message to the source node that communicates with the at least one leaf node, wherein the first PFC notification message is used to notify the source node to stop transmitting a priority packet indicated by the first PFC notification message; or
based on the PFC feedback control information being used to indicate that transmission of the priority packet indicated by the PFC feedback control information is allowed, sending, by the at least one leaf node, a second PFC notification message to the source node that communicates with the at least one leaf node, wherein the second PFC notification message is used to notify the source node that the source node is allowed to transmit a priority packet indicated by the second PFC notification message.
