<p><P>PROBLEM TO BE SOLVED: To provide a packet scheduling device which impartially decides output order in a round without reducing throughput and decides an output flow by a small amount of calculation even in the case of a large number of flows and also to provide its method. <P>SOLUTION: The packet scheduling device includes a buffer memory 1 for storing packets by flow, and a packet transmitting means 3 for transmitting the packet of the designated flow among the packets stored in the buffer memory. The device also comprises a transmission packet deciding means 12 for deciding the competition of the output flows by a DRR system using a heap and designating the decided flow to the packet transmitting means. Thus, control is minutely performed by minimally setting a reference amount, output order in the round is impartially decided, and the transmission flow is determined by the calculation amount of 0 [log<SB>2</SB>(flow number)] in the case of a large number of flows. <P>COPYRIGHT: (C)2003,JPO</p> |
