Abstract: A method and system for service clock transparent transmission in an optical transport network (OTN) are provided. The system includes a service accessing end and an OTN receiving end; the method includes the following steps: the OTN receiving end performs de-mapping operation to an OTN frame after receiving the OTN frame, and performs two-level buffering operation to the service data flow recovered therefrom, a first buffering unit performs a homogenization treatment to the service data flow and then outputs to a second buffering unit, which the second buffering unit outputs the service data flow according to the service clock after receiving the service data flow. After adopting the present invention, it is able to ensure that the quality of the recovered service clock is relatively higher, which meets the customer requirement on the related specification of the service clock.

Abstract: The present invention discloses a method for aligning each scheduling service in an optical transport network. When a cross scheduling unit in a cross board sends service data to each service board, inserts a frame header indication signal into the sent service data, data frames in the sent service data are aligned according to the frame header indication signal, each service board performs a delay to the above service data according to a service delay time when receiving the service data and extracting the frame header indication signal, after the delay time is up, encapsulates the service data to be scheduled and sends to the cross broad to be cached, aligned and scheduled. The present invention also discloses a system for aligning each scheduling service in an optical transport network.

The present invention also discloses a system for aligning each scheduling service in an optical transport network. Thus, before the cross board schedules each path of service, each service board does not need an independent signal wire for providing the frame header indication signal, and is able to basically align frame headers of the service data sent by each path, which is convenient to design the system and provides convenience for capacity expansion of the cross scheduling capacity of the optical transport network.
