    摘要: A method and a device for mapping and demapping a client signal are provided. The method for mapping a client signal includes: dividing a part or all of a payload area of an Optical Channel Payload Unit (OPU) or Optical channel Data Tributary Unit (ODTU) into several sub-blocks, in which the sub-blocks have a size of N bytes, and N is greater than or equal to 1; and mapping a client signal to be transported to the sub-blocks of the payload area with an N-byte granularity. In the technical solutions, when the client signal is mapped, block mapping of the client signal is performed by using a mapping granularity of a block, so that the complexity of the mapping process of the client signal can be reduced, thereby meeting requirements of multi-rate services.
