A method and device for supporting optical transmission network service dispatch in optical synchronization network, the said device includes service board cards (401, 407), backboard interface (404) and a plurality of dispatch units (405, 406), the service board cards (401, 407) process and allot the service signal, and allot the service signal into backboard structure frame based on the bandwidth of pie service signal, and establish the connection with corresponding dispatch units (405, 406) by the (backboard structure frame, then the dispatch units (405, 406) execute the service dispatch. The said dispatch units (405, 406) can work independently each other, and can be added based on the bandwidth of the signal linearly. The present invention can unite the uniform dispatch of the ODU and SDH service, on the base of the existing optical transmission device, and without changing the backboard structure or improving the backboard speed.
