CONGESTION DETECTION APPARATUS, CONGESTION CONTROL APPARATUS, AND CONGESTION CONTROL METHOD THEREOF

摘要

PURPOSE: A congestion detection apparatus, congestion control apparatus, and congestion control method are provided to simply detect congestion by predicting congestion prediction time based on the time conversion of queue length. CONSTITUTION: A congestion detection apparatus monitors a queue which received packet is waited(S210). The congestion detection apparatus computes the speed of the queue corresponding to the length conversion of the queue according to time(S220). The congestion detection apparatus computes congestion prediction time based on the speed of the queue(S230). The congestion detection apparatus transmits a congestion notification signal to neighbor nodes which transmit packets(S240). [Reference numerals] (S210) A transmission standby queue is monitored; (S220) Queue speed calculation corresponding to the length change of a queue according to time; (S230) Congestion prediction time calculation; (S240) Congestion alarm signal is transmitted to a neighbor node
