TCP 혼잡 제어를 위한 동적 RED 알고리즘 = Dynamic RED Algorithm for TCP congestion control

다국어 초록 (Multilingual Abstract)

Recently many studies have been done on the Random Early Detection as an active queue management and congestion avoidance scheme in the Internet. The AQM(Active Queue Management) of traffic congestion involves the policy which drops a packet for congestion avoidance. In this case, router drops one or more packets to improve the network performance before when the output buffer becomes full. In this paper, we overview the characteristics of the RED and the modified RED algorithms in order to understand the current status of these studies. Based on the RED parameter analysis, we propose a Dynamic RED Algorithm for Active Queue Management scheme to cope with this RED weakness. In this algorithm we make three parameters be adjusted depending on the queue status.
