Disclosed are a fiber channel over Ethernet (FCoE) flow control method, device and system, the method comprising: determining whether the flow at an ingress node port of a magnetic array device exceeds a predetermined threshold; if yes, then transmitting a configuration message to a source node device connected to the ingress node port, the configuration message being used for instructing the source node device to adjust the data transmission rate of the applications thereof. The present invention solves the problem in the prior art that the upper layer service in the FCoE network cannot sense link congestion, and improves quality of service of the magnetic array system. |
