국내 통신사업자들이 xDSL 등 초고속 인터넷 액세스 서비스를 왜곡된 요금구조로 경쟁적으로 보급함에 따라 급속히 확산되고 있으나, 엄밀히 원가를 감안한다면 여전히 AO/DI는 인터넷 트래픽 폭증으로 인한 전기통신망의 과부하를 통신사업자가 경제적이며 효과적으로 대처할 수 있는 현실적인 대안이라 할 수 있다. 본 논문은 AO/DI의 동적 채널 할당 및 해지에 있어서 VIA가 권고한 정책보다 효율적으로 대역폭을 할당, 해지할 수 있는 알고리즘을 제안한다. 관찰 시점까지의 누적된 트래픽의 양과 변화를 감안하여 평균 트래픽과 분산을 추정함으로써 트래픽의 변화에 적응하여 채널 할당, 해지 시점을 결정할 수 있으며 트래픽 특성에 따라 매개 변수의 조정을 통하여 D 채널, B 채널의 이용률을 제어할 수 있고 평균 대기시간 등의 성능을 최적화할 수 있음을 보인다. 또한, 이를 기초로 응용 프로토콜을 감지하여 응용이 갖는 고유의 트래픽 특성과 요구사항에 적합한 채널 할당/해지 방안도 제시한다.
