<p>A crossbar (100) includes input queue groups (10,20,30,40) and a distribution processor (110). The input queue groups (10,20,30,40) include multi-step input queues (10a-40a,10b-40b) of data packets whose data transmission destinations are "address W" and "address Y" or "address X" and "address Z" and are provided respectively at input ports A and B and input ports C and D. The distribution processor (110) distributes the data packet input into the input port to input queue group (10,20,30,40) according to the data transmission destinations (that is, "address W", "address Y", "address X", and "address Z") of the input data.</p> |
