Abstract

A network switch with a plurality of crossbar switches that is available to suppress increase in the circuit scale is provided. The network switch has: the plurality of crossbar switches that transfer unit data in a specified format; a receiving side transfer unit that transfers data received from a network to the plurality of crossbar switches in the unit data basis; and a plurality of transmitting side transfer units that transmit data transferred from the plurality of crossbar switches to the network. The receiving side transfer sets a consecutive serial number to the unit data in transfer sequence, and distributes the unit data to the plurality of crossbar switches. Each of the plurality of transmitting side transfer units has a plurality of queues for the respective crossbar switches that stores the transferred unit data, and extracts the unit data with smallest serial number of the unit data stored in the queues when all of the queues store the unit data.
