Abstract
IP 망에서 차별 서비스 구조는 코아 노드에서 클래스별 서비스 기반의 단순한 모델을 적용한다. 그러나, 이러한 단순 처리로 인하여, 망 구조나 프로비저닝은 더욱 복잡하게 되고 서비스 제공자가 동적 프로비저닝이나 효율적인 대역 보장 방법을 제공하려면 시그널링 프로토콜이나 연결 수락 제어 방법이 제공되어져야 한다. 그러나, 이러한 방법은 망의 복잡성을 증가시키게 됨으로 차별 서비스 망에서 복잡하지 않고 대역을 효율적으로 사용할 수 있는 동적 프로비저닝 기법이 연구되어야 한다. 본 논문에서는 차별 서비스 망에서 다양한 서비스 품질 요구 사항을 만족시킬 수 있는 연결 수락 제어 메커니즘으로 대역폭 브로커와 측정 기반 수락 제어 및 가변 영역 대역 관리 방법을 사용하는 DPM2 (Dynamic Provisioning over MBAC and Movable Boundary) 메커니즘을 제안하였다. 또한, ns-2 시뮬레이터를 이용하여 성능 분석을 하였다.
