Abstract
본 논문에서는 Minimum Possible Packet Fair Queueing (MPSFQ)로 명명되는 효율적이면서 구현의 관점에서 용이한 패킷 스케줄링 알고리즘을 제안한다. MPSFQ 알고리즘은 O(1) 의 가상 시간 계산의 복잡도를 가지며 WFQ (Weighted Fair Queueing)알고리즘과 동일한 지연 특성 및 우수한 fairness 특성을 가지고 있다. MPSFQ의 중요한 특징은 시스템 가상 시간은 패킷의 종료 시간에 현재 전송될 패킷이 있는 세션의 최 선두에 있는 패킷들의 가능한 가상 시간의 값 중 최소의 값으로 시스템 가상 시간의 재조정이 이루어지며 시스템 가상 시간의 재조정 시간의 중간에 도착한 패킷의 시스템 가상 시간은 이전 시스템 가상 시간에 두 시간 사이의 실시간을 더함으로써 계산된다. 제안하는 알고리즘이 위와 같은 간단한 알고리즘을 이용하면서도 우수한 지연 특성 및 fairness 특성을 가짐을 수학적인 분석을 통해 증명하고 시뮬레이션을 통하여 그 결과를 확인한다.
