Abstract: In a communication device, a frame received via a port on the reception side is transmitted via a port on the transmission side. A first detector detects linkup of a port on the transmission side. When linkup is detected, a second detector detects a state closer to an overflow of a transmission buffer that accumulates a frame to be transmitted via the port on the transmission side. When a state closer to an overflow is detected, a control unit executes flow control via a port on the reception side when no transmission failure is detected in the port on the transmission side, and the control unit determines non-execution of flow control via the port on the reception side when a transmission failure is detected in the port on the transmission side.
