Abstract: PROBLEM TO BE SOLVED: To provide a congestion control method for a router in an IP packet communication network that can continue communication without much degrading the service quality of connection type TCP(transmission control protocol) data communication in the case that the router controls congestion. SOLUTION: In the default mode, a mode 300 where 'reasonable congestion or no congestion' takes place, selected and the router makes a normal operation. When the queue size reaches (b), the mode transits to a 'suppression of new TCP connection' mode 301, only TCP packets under communication whose TCP connection has already been set up among TCP packets leading to a port are inserted to the queue and new TCP connection request is aborted. In the case of much traffic other than the TCP or an increase transfer rate because the TCP transfer is not early finished, when the queue size is increased and reaches (d), the mode transits to 'TCP windowsize control' mode 302. When no congestion cause exists in this mode, the TCP connection goes to end, the traffic is decreased, the queue size is reduced, and when the queue size is lower than (a), the mode transits to the mode 300.
