A method for transmission service using backplane service buses comprises the following steps: the service received from backplane interface is distributed into different services; the first backplane service bus and the second backplane service bus in the uplink interface of the backplane transmit the different services simultaneously; the first backplane service bus and the second backplane service bus in the downlink interface of the backplane transmit the different services simultaneously. A device for transmission service using backplane service buses comprises the first service board, the second service board, the first cross board, the second cross board and a service distributing unit. The service distributing unit is used to distribute the received service into different services, and control the first and second service boards to transmit the distributed different service to the first cross board and the second cross board simultaneously via different backplane service buses. The first cross board and second cross board transmit the cross service to the second and first service boards simultaneously. The second and first service boards receive the transmitted different service simultaneously.
