Abstract: A service processing method and apparatus and a device is disclosed. Synchronization headers of four 66b code blocks are removed, and a 1-bit code block type indication is added as control information of service data, to be encoded as a 257b code block. This avoids a bandwidth waste caused by the synchronization headers, and improves bandwidth utilization. When a 257b code block stream is mapped to an OSUflex frame, the code block type indication is mapped to an overhead area of the OSUflex frame, the four 66b code blocks from which the synchronization headers are removed are mapped to a payload area of the OSUflex frame, and check information obtained by checking the control information is mapped to the overhead area of the OSUflex frame, so that bit error protection is performed on the control information.

Abstract: This application provides a service processing method and apparatus. The method includes: A transmitting device generates a plurality of transmission frames, where an ith frame in the plurality of transmission frames carries first information, the first information is used to indicate an amount of data of a service that is carried in each of t transmission frames, the t transmission frames include an (i−t)th frame to an (i−1)th frame in the plurality of transmission frames, i−t>0, and t≥1; and sends the plurality of transmission frames to a receiving device. A transmission frame carries information about an amount of data of the service that is carried in a transmission frame before the transmission frame.
