Abstract
This application provides a data transmission method, a communications apparatus, a network device, a communications system, a storage medium, and a computer program product, to resolve a current problem that bandwidth waste is relatively severe when a service is carried based on a FlexE technology. In this application, a frame structure of a fine-granularity service frame is newly defined, so that service data can be transmitted in a time division multiplexing mode by using an Ethernet (ETH) interface.

-27. (canceled)
A method, comprising:
- generating, by a first communications apparatus, a first data stream, wherein the first data stream comprises a plurality of data code blocks,
- wherein the plurality of data code blocks comprise a plurality of first base frames, each first base frame of the plurality of first base frames comprises a corresponding base frame payload, the corresponding base frame payload comprises a corresponding base frame overhead and a corresponding plurality of sub-client sub-slot payloads, the corresponding plurality of sub-client sub-slot payloads comprise a corresponding plurality of first sub-client sub-slot payloads, and the corresponding plurality of first sub-client sub-slot payloads comprise corresponding service data of a first sub-client interface;
- and
- sending, by the first communications apparatus, the first data stream by using a first interface.
A first communications apparatus, comprising:
- a memory storing instructions;
- and
- at least one processor connected to the memory, wherein when the at least one processor executes the instructions, the first communications apparatus is enabled to perform operations including:
- generating a first data stream,
- wherein the first data stream comprises a plurality of data code blocks, wherein the plurality of data code blocks comprise a plurality of first base frames, each first base frame of the plurality of first base frames comprises a corresponding base frame payload, the corresponding base frame payload comprises a corresponding base frame overhead and a corresponding plurality of sub-client sub-slot payloads, the corresponding plurality of sub-client sub-slot payloads comprise a corresponding plurality of first sub-client sub-slot payloads, and the corresponding plurality of first sub-client sub-slot payloads comprise corresponding service data of a first sub-client interface;
- and
- sending the first data stream by using a first interface.
