초록

FIFO 기반 버퍼관리 알고리즘의 공평성 향상과 단순성을 유지하기 위해 새로운 LBO threshold 결정 메커니즘을 제안하였다. 제안한 알고리즘은 활성화된 각 VC의 가중치 합에 따라 LBO를 차별적으로 계산하여 동적으로 적용한다. 이러한 LBO 설정 메커니즘을 DFBA 알고리즘에 적용한 DT-DFBA(Differential Threshold-Differential Fair Buffer Allocation)을 구현하고 실험을 통하여 성능을 평가하였다.

To keep simplicity that needs for GFR service and improve fairness of FIFO based buffer management algorithm, we propose a new LBO threshold decision mechanism. Proposed mechanism uses dynamic threshold that are adjusted according to the sum of active VC's weight. We reformed DT-DFBA(Differential Threshold-Differential Fair Buffer Allocation) algorithm using proposed LBO threshold decision mechanism with existing DFBA algorithm.
