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.

Abstract: This application provides an isolation and recovery method and related network device for a case when one or more physical layer apparatuses (PHYs) in a flexible Ethernet group (FlexE group) are faulty. In the method, if a network device determines that a first overhead block corresponding to each current available PHY is stored in a corresponding memory, the network device determines that a FlexE group meets a PHY alignment condition, and starts to simultaneously read cached data from all memories. Therefore, there is no need to insert local fault LF code blocks to all clients, and there is no need to recreate a group. This effectively reduces the impact of a faulty PHY on client services carried by a normal PHY.

Abstract: In an embodiment, the application provides a flexible Ethernet (FlexE) communication method, which includes: receiving, by a first network device by using a FlexE group, n first overhead blocks sent by a second network device, the FlexE group comprising n physical layer apparatuses (PHYs); and storing, by the first network device, the n first overhead blocks in n memories in the first time period. The method further includes simultaneously reading, by the first network device, the n first overhead blocks from the n memories, after a preset duration T starting from a moment at which a first overhead block is stored in a corresponding memory. The first overhead block is a last stored first overhead block in the n first overhead blocks, the duration T is greater than or equal to one clock cycle.
