Embodiments of the present invention provide a network congestion control method, a device, and a system. The method includes: receiving a first congestion control message, where the first congestion control message carries a 5-tuple of a packet that causes congestion; obtaining a flow identifier of the packet based on the 5-tuple of the packet that causes the congestion; generating a second congestion control message, where the second congestion control message carries the flow identifier corresponding to the 5-tuple; and sending the second congestion control message to a source node of the packet. In the embodiments of the present invention, a network congestion problem of a layer 3 IP network can be resolved. In technical solutions provided in the embodiments of the present invention, when congestion is detected in the network, the 5-tuple of the packet that causes the network congestion is obtained, the flow identifier of the packet that causes the network congestion is obtained based on information about the 5-tuple, and then a congestion control message is generated and is sent to the source node of the packet, to instruct the source node to reduce a rate of a packet that has the flow identifier. The technical solutions may be applied to a layer 3 network.
