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: This application discloses a method and an apparatus for updating a manner of processing a packet of a service flow. The method includes a first packet of the service flow is forwarded by using a first service function chain (SFC). A control node obtains a flow identifier and indication information from a service function (SF) node of the first SFC, where the indication information is used to indicate a manner of processing a second packet of the service flow, the flow identifier is used to identify the service flow. The control node obtains the manner of processing the second packet according to the indication information, and sends the flow identifier and the manner of processing the second packet to the processing node, where the manner of processing the second packet does not include forwarding the second packet along the first SFC.

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 disclosure relates to a data transmission method, apparatus, and system, and belongs to the field of communications technologies. The data transmission method includes: obtaining, by a first node, m (m≥2) first FlexE clients, mapping the m first FlexE clients to one second FlexE client, and transmitting data of the second FlexE client to a second node, where data of each first FlexE client occupies a fixed timeslot of the second FlexE client, and the second node is different from the first node. In this disclosure, a problem in a related technology that a relatively fine granularity of a FlexE client imposes a relatively strict requirement on data processing performance of a node is resolved, and a plurality of first FlexE clients are mapped to one second FlexE client.
