Client signal transmission method, device and system and computer-readable storage medium

A client signal transmission method, comprising:

• acquiring an optical transport network frame, wherein the optical transport network frame carries a predetermined container and configuration information of the predetermined container;
• demapping, according to the configuration information of the predetermined container, a client signal data stream from first code blocks corresponding to the predetermined container in a payload area of the optical transport network frame, wherein the first code blocks are obtained by dividing the payload area of the optical transport network frame;
• identifying and deleting special code blocks in the client signal data stream to obtain the predetermined container;
• and
• performing frame alignment on the predetermined container and acquiring a client signal from a payload area of the predetermined container.

A client signal transmission apparatus, comprising:

• a processor and a memory storing processor-executable instructions which, when executed by the processor, are configured to:
• map a client signal into a predetermined container corresponding to the client signal;
• map the predetermined container into a corresponding number of first code blocks in a payload area of an optical transport network frame and insert special idle code blocks during the mapping for rate compensation, wherein the first code blocks are obtained by dividing the payload area of the optical transport network frame;
• and
• to send the optical transport network frame carrying the predetermined container and configuration information of the predetermined container.
