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: A delay measurement method is disclosed. A first communication apparatus obtains a first moment, where the first moment is a timestamp at which the first communication apparatus inserts an operation, administration and maintenance OAM block; and the first moment is greater than or equal to a moment at which the first communication apparatus receives a first service bit flow, the first moment is less than a moment at which the first communication apparatus inserts a one-way delay measurement 1DM message or a two-way delay measurement 2DM message into a first block flow, the first service bit flow carries a first fine granularity service, and the first block flow is obtained based on the first service bit flow; and the first communication apparatus sends first moment to a second communication apparatus, where the first moment is for measuring a delay between the first communication apparatus and the second communication apparatus.

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.

Abstract: This application provides a data stream processing method and a network element device. The method includes: obtaining, by a first network element device, a first data stream, where the first data stream includes a first data unit and a first data padding unit; and adjusting, by the first network element device, a quantity of second data padding units in the first data stream, where a relative position of the first data unit and the first data padding unit in the first data stream is the same as a relative position of the first data unit and the first data padding unit in a second data stream, and the second data stream is an adjusted first data stream. When adjusting a rate, the first network element device does not add or delete the first data padding unit in the first data stream.

Abstract: A method includes: receiving a first result obtained by performing BIP check on a sent first to-be-checked bit stream; performing BIP check on a received second to-be-checked bit stream to obtain a second result, where the second to-be-checked bit stream is a bit stream received by a receiving device after the first to-be-checked bit stream is transmitted; detecting a type of a control block in the second to-be-checked bit stream, and determining a third result based on impact of the type of the control block on a BIP check result; comparing the first result, the second result, and the third result; and if the first result is different from the second result, the first result is different from the third result, and the second result is different from a predetermined result, determining that a bit error occurs when the first to-be-checked bit stream is transmitted.
