A method for multiplexing and demultiplexing low bit rate services includes dividing an OTN frame into a plurality of time slots and allocating the plurality of time slots to the low rate services according to the bit rate of the low rate services; asynchronously mapping a synchronous service to the time slots allocated to the synchronous service if it is determined that the low bit rate service is a synchronous service; encapsulating the low bit rate service and mapping the low bit rate service to the time slots allocated to the low bit rate service if it is determined that the low bit rate service is not a synchronous service. A multiplexing apparatus includes a time slot division and allocation module and a mapping module. An apparatus for demultiplexing low bit rate services includes an overhead resolving module, a synchronous service recovery module, a data service recovery module, an unknown type service recovery module. In accordance with the processing procedures of the method and apparatus for multiplexing low bit rate services, the method and apparatus for demultiplexing low bit rate services may adopt a different processing approach for different types of low bit rate service and obtain a corresponding service. The present invention allows the OTN to realize the bearer of the low bit rate data service and achieves the multiplexing and demultiplexing of hybrid services. |
