<p>PURPOSE:To suppress the influence of a congested state such as congestion to its minimum by informing congested state information to the other packet exchange node at the time of occurrence of congestion and allowing the other packet exchange node receiving the information to regulate packet data in a communication route directing a transmission line where the congestion or the like, occurs. CONSTITUTION:A communication route control means 105 is formed in each transmission line 106 stored in a self-packet exchange node and has a selector means for storing information indicating whether the sending of packet data is being regulated at present in each communication route included in a self- transmission line or not and storing the packet data 108 to be sent in a regulation waiting buffer means when the regulation is executed, or storing the packet data 108 to be sent in a sending waiting buffer means when the regulation is not executed. At the time of receiving congested state canceling information from the other packet exchange node, packet data stored in the regulation waiting buffer means are sent to the self-transmission line, and in other cases, packet data stored in the sending waiting buffer means are sent to the self- transmission line.</p> |
