<p>PURPOSE:To continue a data transmission only by means of the replacement of data to indicate a destination even when a computer system is downed by constituting a multistage connecting network so as to define a detouring route even when a fault is generated on a normal route to execute a connection between data processors. CONSTITUTION:When the fault is generated at, for example, a basic connection linking circuit b1 in a normal circuit 101, for the normal circuit 101, the connection is interrupted, and a data transfer from a controller X0 to a controlled device Y0 is suspended. In such a case, as a carrying route from the controller X0 to the controlled equipment Y0, and alternate route 102 to be indicated by alternate long and short lines is re-defined by correcting the data to indicate the destination so as to pass, for example, basic connection linking circuits a1, a4, b17, b18, c3 and c2. As a result, by re-activating the multistage connecting network device, the data can be transferred from the controller X0 through the detouring route 102 to the controlled equipment Y0.</p> |
