<p>PROBLEM TO BE SOLVED: To provide a network system that can properly operate when a packet is transmitted over a network under the control of a different controller.SOLUTION: A network system includes a controller 200 that controls a plurality of switches 300 and an integrated controller 100 that controls the plurality of controllers 200. The integrated controller 100 transmits, to the plurality of controllers 200, information on a boundary port, which is a port for transmitting, to switches 300 under the control of one controller 200, packets from switches 300 under the control of the other controller 200. The controllers 200 transmit a request according to the information on the boundary port to the switches 300 when paths for the packets transmitted to the switches 300 under the control of the controllers 200 include the boundary port.</p> |
