통합 서비스 제공을 위한 QoS기반 패킷 스케줄링 알고리즘

다국어 초록 (Multilingual Abstract)

In this paper, we investigate the scheduling algorithm of router system for Internet service based on the quality-of-service(QoS) level of the input source traffics. We suggest an approprite scheduling algorithm in order to satisfy their QoS requirements for the loss-sensitive traffic and delay-sensitive traffic. For this purpose, we first study the service requirements of the multiplexer in Internet and the definition of QoS based on the ITU-T white recommendations. Second, we suggest a functional architecture of the multiplexer and the scheduling algorithm to satisfy various QoS requirements for Internet service. Finally, the performance measures of interest, namely steady-state packet loss probability and average delay, are discussed by simulation results.
