Abstract: PROBLEM TO BE SOLVED: To simplify the configuration of switch and a control method and to stably and easily execute control by outputting a cell, which is read out by an input cell selecting operation, through a bus dedicated to output under the control of switch module control means. SOLUTION: Plural switch output multiplexing means 20 are provided and this multiplexing means 20 performs the input cell selecting operation for inputting respective cells such as continuous cells containing cell data, cell enable signal (CEN), cell start signal (SOC) and synchronizing clock from an input port driving means 11 of plural line interface means 10, temporarily storing the inputted cells and afterwards, preferentially reading out the temporarily stored cells corresponding to the means 11 having high frequency of generation. Then, this read-out cell is outputted through a bus B3 dedicated to output under the control of switch module control means 70. Thus, the amount of hardware required for buffer configuration can be decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a fixed length packet switching device using a multiplexer and a demultiplexer provided with the structure of an output buffer type and provided with a flow control structure mutually between them so as to protect the switching device from temporary overflow generation at an output terminal and improve the entire performance. SOLUTION: An IPDU 31 is an input port driving unit and an SIDU 32 is a switch input demultiplexer unit. An SOMU 33 inputs respective packets routed through the respectively fully interconnected input links of the SIDU, gathers them to an output buffer and multiplexes the gathered packets so as to be outputted as a packet flow.
