PROBLEM TO BE SOLVED: To reduce a communication delay at proxy TCP connection which is performed by a switch in a network of a CD separation type, such as an open flow network.SOLUTION: A controller sets a flow entry, in which a rule and an action to control uniformly packets as a flow are defined, to each of a plurality of switches. On receipt of a SYN packet from a transmission source host, each switch requests the controller to calculate a route. Each switch, if it is a head switch on a communication route obtained as a result of the route calculation, performs proxy TCP connection to a transmission destination host. If the switch is not a head switch on the communication route, the switch transfers the SYN packet to perform proxy TCP connection between the head switch and the transmission destination host. |
