摘要： Embodiments of this application provide a data transmission method, a communications device, and a storage medium to reduce a quantity of cross-connections of an intermediate node in a network. In the embodiments of this application, Q first code block streams that are obtained are multiplexed into one second code block stream for transmission, a coding type of the first code block streams is M1/N1 bit coding, a coding type of the second code block stream is M2/N2 bit coding, and bits corresponding to code blocks in the Q first code block streams are carried in a payload area of a code block in the second code block stream. In other words, in the solutions provided by the embodiments of this application, the code block streams are multiplexed and demultiplexed based on a code block granularity. In this way, the second code block stream traverses at least one intermediate node to reach a communications device on a demultiplexing side, and the intermediate node does not perform demultiplexing on the second code block stream. Therefore, a quantity of cross-connections of the intermediate node in the network can be reduced.

摘要： A communication method, a communications device, and a storage medium are disclosed, to implement a flexible Ethernet protocol-based communication solution. In embodiments of this application, a first communications device receives, by using a link corresponding to a first FlexE group, first indication information sent by a second communications device, where for a slot in N slots of the first FlexE group, the first indication information is used to indicate that the second communications device has assigned a FlexE client to the slot, or used to indicate that the second communications device has not assigned a FlexE client to the slot; and the first communications device assigns the FlexE client to the slot in the N slots of the first FlexE group, or cancels, based on the first indication information, the FlexE client that has been assigned to the slot. In this way, the flexible Ethernet protocol-based communication solution is implemented. Further, because a slot assignment status of a communications device may be updated based on a slot assignment status indicated by indication information, slot assignment flexibility is improved.
