Abstract
In a data transmission device and method provided with duplexed switches outputting frames in the order of input for continuing the communication without instantaneous interruptions even though one of the switches is faulted, input interfaces generate frames in which every time data is inputted, input order information indicating the input order is added to the data together with unique information of each input interface and providing the frame generated to the switches in parallel. At least one output interface sequentially stores the frames outputted from the switches for every unique information and selects a first arrived frame among the frames stored with same input order information.
