<p><P>PROBLEM TO BE SOLVED: To provide a congestion control apparatus capable of reducing a packet discarding rate by enabling a behavior of an average buffer length to be predicted in early timing, and to provide a congestion control method. <P>SOLUTION: A congestion control apparatus 50 includes: a SYN/ACK detecting part 6 for detecting a packet, in response to a connection request from a connecting side, obtained by combining a connection permission from a connected side and the connection request; a mark detecting part 7 for detecting a predetermined mark included in a data packet; a packet/mark counting part 8 for counting the number of packets and the number of marks; a traffic variation-predicting part 10 for predicting variation of traffic based on the results counted by the packet/mark counting part 8, respectively; a RED parameter-varying part 11 for varying a parameter relating to random initial detection based on an amount of variation of the average buffer length predicted by the traffic variation predicting part 10; and a control part 9 for controlling the respective parts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
