This disclosure relates to the field of data communication, and provides a network congestion notification method, an agent node, and a computer device. When receiving a first data packet, an agent node adds a source queue pair number to a first data packet to obtain a second data packet, and sends the second data packet to a receive end by using a network node. In a process of forwarding the second data packet, if the network node detects network congestion, the network node generates a first congestion notification packet carrying the source queue pair number, and sends the first congestion notification packet to the agent node. Further, the agent node sends the first congestion notification packet to a transmit end, so that the transmit end decreases a sending rate of a data flow to which the first data packet belongs.
