This application discloses a service data processing method and apparatus, to resolve a problem of low bandwidth utilization in the conventional technology. A dynamic framing method is used. When a transmission rate of an OTN data frame increases, a length of a payload area constantly increases, while a length of an overhead area does not increase. In other words, in OTN data frames at different transmission rates, lengths of overhead areas are fixed. As the transmission rates of the OTN data frames increase, lengths of payload areas constantly increase. In this way, when the rate increases, overheads do not occupy more bandwidths, thereby improving bandwidth utilization.

Provided are a client signal transmission method, apparatus and system and a computer-readable storage medium. The method includes mapping a client signal into a predetermined container corresponding to the client signal; mapping the predetermined container into the corresponding number of first code blocks in a payload area of an optical transport network frame and inserting special idle code blocks during the mapping for rate compensation, where the first code blocks are obtained by dividing the payload area of the optical transport network frame; and sending the optical transport network frame carrying the predetermined container and configuration information of the predetermined container.

The payload area includes the first payload area and a second payload area. The second payload area carries the compressed data stream, and the first payload area carries a forward error correction (FEC) code.
