CROSS-POINT SWITCH CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a cross-point switch controller which can prevent a port from entering a deadlock state due to line blocking and improve communication efficiency between ports. SOLUTION: After a cross-point switch is controlled at a connection request sent from a port controller to connect a connection-source port to a connection- destination port, a packet of connection establishment response including an establishment flag representing that whether or not the connection source and connection destination have been connected together is sent back to the port controller having sent the packet of the connection request.
