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: In a data transmission method, each ring network interface is associated with a ring identifier, and a ring-incoming packet carries a ring identifier of a ring network interface through which the packet is first forwarded. When a node in a ring network detects a link fault in a process of transmitting a packet, the node determines, with reference to a ring identifier and a wrapping identifier carried in the packet, to perform wrapping or discard the packet. According to the method, two sub-ring networks of a dual-ring coupled ring network can be allowed to separately implement one time of wrapping.

Abstract: This application provides a data transmission method and apparatus, and relates to the field of communications technologies. The method includes: obtaining a plurality of code block streams; distributing, based on a preset multiplexing sequence, code blocks in the plurality of code block streams by slots, to form a single, interleaved code block stream from the plurality of code block streams; and segmenting and encapsulating the single, interleaved code block stream, to generate at least one frame. By utilizing time division duplexing techniques, a data transmission delay of the code block streams can be reduced.

Abstract: Example methods and apparatus for processing a bit block stream are described. One example method includes obtaining a first to-be-processed bit block stream and mapping the first to-be-processed bit block stream into at least two slot bit block streams. The at least two slot bit block streams include a first slot bit block stream and a second slot bit block stream. The first slot bit block stream includes a first boundary bit block and a second boundary bit block. The second slot bit block stream includes a third boundary bit block and a fourth boundary bit block. N first bit blocks exist between the first boundary bit block and the second boundary bit block. N first bit blocks exist between the third boundary bit block and the fourth boundary bit block. The first bit block is a non-idle bit block.
