<p>PURPOSE:To suppress the increase of a quantity of hardware for the increase of the number of input/output lines by constituting plural unit switches annularly, and circulating routing control information with communication information as computing the routing control information. CONSTITUTION:The communication information inputted to the input lines (111...11N), after being parallel/serial-converted at input controllers (121...12N), are transferred to the unit switches (131...13N) with the routing control information. The routing control information and the communication information are transferred between each of the unit switches (131...13N), and at that time, the routing control information is computed at every transfer, and is changed to new routing control information. Output controllers (141...14N) fetch the communication information by detecting the routing control information, and output them after applying parallel/serial conversion.</p> |
