본 논문에서는 패킷 네트워크에서의 성능 품질을 개선하기 위한 접근방식으로 적응형 절대적/상대적 지연 차별화 방식을 제안한다. 제안된 방식은 타임 슬롯의 시작점에서 추후 도착될 트래픽의 양을 예측하여 지연 차별화 기능을 수행한 후 해당 타임 슬롯의 종단점에서 실제로 입력된 트래픽의 양을 실측하여 예측치와 실측치간의 차이를 도출하고 이를 다음 타임 슬롯의 지연 차별화 동작에 반영하여 성능 개선을 추구하는 것이 특징이다.. 제안된 방식은 지속적으로 예상 트래픽의 오차를 보상함으로서 지수형 트래픽 뿐만 아니라 버스트 트래픽에 대하여 기존 방식에 비하여 우수한 적응성을 제공한다. 모의실험을 통하여 제안된 방식은 엄격한 지연 목표를 충족할 뿐만 아니라 기존 방식에 비하여 트래픽 변동에 우수한 적응성을 제공함을 입증한다.
