Abstract

A first node and a second node transmit packets to a third node via a switch. The packets are buffered in a Tx buffer in the switch and then transmitted to the third node. When the third node detects a sign of congestion at the Tx buffer based on the reception frequency of the packets, it is recognized, from transmitter addresses included in the received packets, that the nodes transmitting the packets to the third node are the first node and the second node, and a control packet for a transmission stop request is transmitted to the first node and the second node. On receiving the control packet for a transmission stop request, the first node stops transmission of only packets addressed to the third node. On receiving the control packet for a transmission stop request, the second node stops transmission of only packets addressed to the third node.
