FLEXIBLE ETHERNET (FLEXE)-BASED SERVICE FLOW TRANSMISSION METHOD AND APPARATUS

摘要

This application provides a method and an apparatus for transmitting a service flow based on flexible Ethernet FlexE. The flexible Ethernet includes a first network device and a second network device, and the first network device and the second network device transmit the service flow by using a first FlexE group. The method includes: sending, by the first network device, a first FlexE overhead frame to the second network device, where the first FlexE overhead frame includes FlexE group adjustment identification information and PHY information of a physical layer PHY included in a second FlexE group; receiving, by the first network device, a second FlexE overhead frame sent by the second network device, where the second FlexE overhead frame includes FlexE group adjustment acknowledgment identification information; adjusting, by the first network device, the first FlexE group to the second FlexE group; and sending, by the first network device, the service flow to the second network device based on the second FlexE group, to dynamically adjust a FlexE group.
