<p>PURPOSE:To prevent the congestion of a network by using a controller with a means which delays re-sending operation by a specified time when a reception state confirmation signal shows that reception is disabled. CONSTITUTION:A packet arriving from a terminal 101 is stored in a buffer 102 temporarily. A transmitter 103 outputs it. A packet receiving station 110 receives a packet address to the station among packets sent through the network 107 and outputs it to a terminal 113. The station 110 returns the reception confirmation signal for the packet to the network 107 immediately. A transmitting station receives the reception confirmation signal by a receiver 104 and outpus a signal indicating whether reception confirmation is performed or not to a conrroller 105. The controller 105 when receiving a signal showing the success of the reception erases this packet. On the other hand, when a signal showing the failure in the reception is received, a resent signal is outputted to the transmitter 103 after the specified delay time and the packet stored in the buffer 102 is sent out again to the network 107.</p> |
