Abstract
본 논문에서는 광대역통합 네트워크(BcN:Broadband Convergence Network)을 이용하는 사용자에게 서비스품질을 제공하기 위한 스케쥴링 기법의 성능을 비교, 분석한다. 이를 위하여 트래픽의 등급별 분류, 입력큐에서의 처리, 등급별 가중치 부여 등과 같은 주요 서비스품질 관리 기법들을 분석하고 최근 멀티미디어 인터넷 통신을 위해 우선 고려되고 있는 주요 스케쥴링 기법(Round Robin, Priority, Weighted Round Robin)들의 동작원리를 분석한다. NS-2를 이용한 시뮬레이션을 통하여 각 스케쥴링 기법들의 성능을 분석한 결과, 단순히 하나의 서비스 등급에 대하여 Priority 스케쥴링 기법을 사용하는 것보다 등급별로 적절한 가중치를 두어 자원을 사용하는 것이 바람직함을 알 수 있다.Scheduling Algorithms for QoS Provision in Broadband Convergence NetworkKi-Sung Cho* Hyun-Chul Shin*** Jang-Hee Lee****
