Abstract: Embodiments provide a protection switching method and system, a network device, and related communications technologies. In various embodiments, if n links carrying a client service are unavailable in a FlexE link group, at least one protection link can be selected, by a first network device, from links other than the n links in the FlexE link group. A calendar request can be sent, by the first network device, to a second network device over the protection link. A calendar acknowledge can be sent by the second network device over the protection link and can be received, by the first network device. A transmission of the client service can be switched over from the n links to the protection link. In the present invention, an application requirement of the FlexE for protection switching is satisfied.

Abstract: The present disclosure relates to operation, administration and maintenance (OAM) data transmission methods and apparatuses. One example method includes obtaining, by a first node, a first data flow of a client. The first node inserts an OAM data block in the first data flow of the client to obtain a second data flow of the client, where the OAM data block is a 64B/66B code block that carries OAM data. The first node distributes the second data flow of the client to at least one slot of a channel corresponding to the client.

Abstract: This application provides a radio fronthaul interface signal transmission method, a device, and a system. A network device obtains a radio fronthaul interface signal including a plurality of code blocks. The network device maps the radio fronthaul interface signal to M flexible Ethernet FlexE service layer timeslots to generate a FlexE signal, where the FlexE service layer timeslots are determined based on a rate of the radio fronthaul interface signal, and M is a positive integer greater than or equal to 1. The network device sends the FlexE signal to one or more physical lanes. The radio fronthaul interface signal such as a CPRI signal, an eCPRI signal, or an NGFI signal is carried by using FlexE, and the FlexE service layer timeslots are divided based on the rate of the radio fronthaul interface signal.
