All IoT devices that pass through the test packet are determined as the transmission path of the data packet, which can visually view all the transmission paths of the data packet, and can facilitate the user to select an optimal transmission path from the transmission path and appear in the transmission process of the data packet. When it is wrong, it is difficult to reduce the positioning analysis.

Optionally, as another embodiment of the present invention, each first feedback information carries ID information of a next hop IoT device of the test data packet. The controller 720 can determine the transmission path of the data packet according to the ID information of the next hop IoT device of the test data packet carried by the first feedback information, and the ID information of the IoT device that receives the test data packet, which can be more convenient. Know the transmission path of the data packet in the Internet of Things.
