Abstract
A signals is input to k (k being an integer 2 or greater) switching units, and is output to one of n (n being an integer of 2 or greater) output ports. The n×k splitter units each corresponding to the respective output ports of the respective switching units split the signals having been output from the corresponding output ports into nsignals. A plurality of receivers are connected to the k splitter units that split signals having been output from the k respective switching units. The combinations of the splitter units to which the respective receivers are connected are different. A receiver accepts received signals when having received the signals from all of the connected k splitter units, but discards received signals when having received the signals from only a part of the connected k splitter units. A control unit controls the output ports to which the respective switching units output signals in accordance with the receiver serving as the destination of data.
