Abstract: A first network device determines configuration information of a target flexible Ethernet (FlexE) group to be adjusted, and adjusts the target FlexE group synchronously with a second network device based on the configuration information of the target FlexE group. The second network device communicates with the first network device through a physical layer link in the target FlexE group. The configuration information of the target FlexE group includes a backup FlexE group number and a backup FlexE map of the target FlexE group, and the backup FlexE map includes information about the physical layer link in the target FlexE group. The first network device and the second network device perform synchronous adjustment.

Abstract: Embodiments of this application provide a packet forwarding method, a packet processing method, and a device, to determine a network slice that corresponds to a packet and that is of a transport network. The packet forwarding method includes the following steps: A first device obtains a first packet. The first device is a network device in an access network or in a mobile core network. The first device determines network slice mapping information based on the first packet. The first device generates a second packet based on the first packet. The second packet includes the network slice mapping information. The first device sends the second packet to a second device. The second device is a network device in a transport network.

Abstract: A first network device determines configuration information of a target flexible Ethernet (FlexE) group that needs to be adjusted, and adjusts the target FlexE group synchronously with a second network device based on the configuration information of the target FlexE group. The second network device communicates with the first network device through a physical layer link in the target FlexE group. The configuration information of the target FlexE group includes a backup FlexE group number and a backup FlexE map of the target FlexE group, and the backup FlexE map includes information about the physical layer link in the target FlexE group. The first network device and the second network device perform synchronous adjustment. In this way, embodiments of this application provide a management solution for losslessly and dynamically adjusting a FlexE group, to avoid impact on a service and implement FlexE group adjustment in various scenarios.
