A packet measurement method includes obtaining, by a network device, reverse measurement indication information that is used to indicate a request to measure a reverse packet flow of a first packet flow, after receiving the first packet flow, adding, by the network device, the reverse measurement indication information to a packet in the first packet flow, and sending, by the network device, the packet that is in the first packet flow and that carries the reverse measurement indication information. By adding the reverse measuring indication information to the packet in the first packet flow, the method indicates a request to another network device on the packet forwarding path to measure the reverse packet flow of the first packet flow. Measurement on bidirectional packet flows is implemented through one measurement deployment.

A port mode adaptation method includes a network device determining a status of a port on the network device. The method includes the network device setting a mode of the port to an Ethernet interface mode if the status of the port satisfies a first condition. In this way, when the network device identifies the mode of the port on the network device as the FlexE interface mode, and there is no link at the FlexE shim of the port, the network device may determine that a mode used by a port interconnected with the port is not a FlexE interface mode. In this case, the network device may adaptively set the mode of the port to the Ethernet interface mode, to ensure that the port on the network device can use a same mode as another port interconnected with the port.

A data processing method in a data processing device is provided. First to-be-processed data input into a neural network are obtained. Iterative training is performed on the neural network for a first preset number of times by using first target data in the first to-be-processed data, to obtain a seed model of the neural network. First newly added data generated after an elapse of time corresponding to the first time window is obtained, and the first newly added data and the first to-be-processed data are combined into second to-be-processed data. Iterative training is performed on the seed model for a second preset number of times by using second target data in the second to-be-processed data, to obtain a first incremental model of the neural network. A first preset area overlaps between the second time window and the first time window. The first incremental model online is published.

A pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end is adjusted. A signal received quality report which is obtained according to the pre-distortion coefficient before adjustment is analyzed and fed back by a receiving end and a signal received quality report that is obtained according to the pre-distortion coefficient after adjustment and fed back by the receiving end. The analysis determines a variation situation of signal received quality of the receiving end. If the signal received quality of the receiving end becomes better, the pre-distortion coefficient after adjustment is used as the pre-distortion coefficient corresponding to the transmit power currently set by the transmitting end. The process then returns to the step of adjusting a pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end.
