Crossbar switch, method for controlling operation thereof, and program for controlling operation thereof

A method for operation control of a crossbar switch, the crossbar switch comprising nodes that are cascade connected with each other in a plurality of stages and a plurality of node lines through which received data to be produced flow, each node having a node controller, the method comprising the steps of:

• generating an address information from identification information of a node line on which the received data is to be produced, the address information representing a relative position of the node controller which is to be actuated;
• supplying the address information to a node of an initial stage of a target node line;
• determining, by respective node controllers present in each node of the target node line to which the address information is supplied, whether the received address information represents a specific value,
• producing the received data present on the target node line when it is determined that the specific value is represented;
• and
• generating a new address information by changing the received address information by a predetermined value, and supplying this new address information to nodes of subsequent stages,
• wherein said received address information is configured to designate data that is output from a node of a final stage of the tar et node line.

A program stored on a computer-readable medium for operation control of a crossbar switch, the crossbar switch comprising nodes that are cascade connected with each other in a plurality of stages and a plurality of node lines through which received data to be produced flow, each node having a node controller, the program being carried out by a computer having mounted thereon the crossbar switch to operate each node controller to:

• (1) receive address information for directly or indirectly specifying a relative position in which a target node controller is located, wherein said address information is configured to designate data that is output from a node of a final stage of the node line on which the address information is input;
• (2) determine whether the received address information represents a specific value, and produce data present on a respective node line when it is determined that the specific value is represented;
• and
• (3) generate new address information by changing the received address information by a predetermined value and supply the new address information to nodes of subsequent stages.
