Abstract: This application discloses a bit error indication method for a service stream and a communication apparatus, so that when a quantity of bit errors that is counted inside a device exceeds a preset threshold, it can be ensured that the device continues to work normally. The method includes: A network device receives a first signal stream from a first node by using N slots of a first bonding group, determines a first check value based on a first check code in the first signal stream, determines a second check value based on the first check value and a current check value, and sends a second signal stream to a second node by using M slots of the first bonding group. The second signal stream includes a target check value determined based on the second check value.

Abstract: This application discloses a block group loss determining method and an apparatus. The method includes: A transmit end obtains at least two block groups, and sends the at least two block groups to a receive end. The receive end receives the at least two block groups, obtains a receiving quantity of first block groups between a first boundary block group and a second boundary block group in the at least two code groups, then obtains a target quantity of first block groups between the first boundary block group and the second boundary block group, and determines a quantity of lost block groups based on the receiving quantity and the target quantity.

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.

Abstract: This application discloses a code block identification method and related apparatus. The method includes: obtaining a code block stream, where the code block stream includes a first code block; determining a to-be-identified bit pattern and comparing the to-be-identified bit pattern with a template bit pattern to obtain a quantity of inconsistent bits; and identifying the first code block as a first boundary code block when the quantity of inconsistent bits is less than or equal to a first threshold. The to-be-identified bit pattern includes a first bit pattern and corresponds to the first code block. The template bit pattern includes a first template bit pattern and corresponds to the first boundary code block.

Abstract: The technology of this application relates to a rate adaptation method and apparatus. The method includes, when a rate adaptation requirement exists, inserting a rate adaptation code block only between two adjacent code blocks whose code block relationship meets a preset condition, or deleting only a rate adaptation code block between two code blocks whose code block relationship meets a preset condition. In this way, it can be ensured that correctness of parsing a packet by a receive side after the receive side receives the packet is not affected by rate adaptation, and reliability of rate adaptation can be improved.

Abstract: A communication method, device, and a storage medium to resolve a problem that information about a clock frequency and a clock phase of a service cannot be correctly transmitted to a receiver or correctly recovered because transparent transmission of the information about the clock frequency and the clock phase of the service cannot be implemented. Because a value of k based on a reference data unit is inserted into a second data flow, and the value of k can indicate a quantity of third data units included between a second data unit and the reference data unit in a first data flow, a receive end device can completely recover the first data flow based on the value of k.

Abstract: Embodiments of this application provide a communication method, a communications device, and a storage medium, to process an invalid block in a data stream. In embodiments of this application, N first block streams are obtained, where N is a positive integer. When there is an invalid block in the N first block streams, the invalid block in the N first block streams is converted into a target block, to obtain a to-be-sent block stream. Then, the to-be-sent block stream is sent. Because the invalid block in the block stream is checked and converted into the target block, an error that occurs in service data at a receive end and that is caused by the invalid block can be reduced.
