Disclosed are a method and device for implementing mapping and de-mapping of a client signal, said method including the following steps: dividing part or all of the payload area of the optical channel payload unit or optical channel data tributary unit into several sub blocks, the size of said sub block being N bytes, and N being greater than or equal to 1 (210); setting N bytes as the granularity and mapping the client signal, which is waiting to be sent, to the sub blocks of the payload area (220). When performing client signal mapping, the technical solutions adopted by the embodiments of the present invention use blocks as the mapping granularity to perform block mapping of the client signal, thus reducing the complexity of client signal mapping processing, and meeting the requirements of multi-rate service. |
