Disclosed are a method and device for selecting a forwarding path. The method comprises: if a data message to be sent to a target device is a starting message of a short flow where the data message is located, a sender device selecting, from a plurality of paths, a path with a low load, so as to forward the data message, and setting a forwarding decision of the flow where the data message is located as the selected path. The load of each path is the greater of the load of the flow received from the sender device by a corresponding intermediate device and the load of the flow sent to the target device. The load of the flow sent to the target device by the intermediate device is measured by the target device. The target device finds, by means of measurement, that the load of the flow from the intermediate device is equal to the load of the flow sent to same by the intermediate device. Load balancing based on a short flow can be realised only by providing the relevant functions on one type of device.
