Congestion processing method, apparatus, network device and storage medium

A network device, comprising a processor and a machine-readable storage medium, where the machine-readable storage medium stores machine-executable instructions that can be executed by the processor, and the processor is caused by the machine executable instructions to implement the following operations:

• receiving a first data packet carrying a congestion mark through a target port;
• searching, in a preset greedy flow table, a target table entry that includes target flow information carried in the first data packet and an identifier of the target port, and the preset greedy flow table stores flow information of a data flow whose traffic is greater than a preset traffic threshold and an identifier of a port that receives a data flow corresponding to the flow information;
• processing, if the target table entry is found, the first data packet;
• removing, if the target table entry is not found, the congestion mark carried in the first data packet to obtain a second data packet, and processing the second data packet,
• wherein each table entry in the preset greedy flow table is set with an initial active value, the processor is caused by the machine executable instructions to further implement the following operations:
• subtracting, if the target table entry is found, a first preset value from a current active value of the target table entry, to obtain an adjusted active value of the target table entry;
• deleting, if the adjusted active value of the target table entry is less than or equal to a second preset value, the target table entry from the preset greedy flow table.
