초록
차세대 네트워크(NGN)는 QoS가 지원되는 광 대역 전달 망에서 세션 및 비-세션 서비스를 지원하기 위한 패킷 기반의 융합 망이다. NGN에서 네트워크 사용자에 따라 차별화된 서비스를 제공하기 위해서는 QoS 기반 자원제어가 이루어져 한다. 본 논문에서는 세션 및 자원제어 지연을 최소화하기 위하여 NGN 자원제어 인터페이스에 병행형 제어 스킴을 정의하였다. 시뮬레이션을 통하여 기존 및 제안된 NGN 제어 스킴들의 제어지연과 완료율을 측정 및 분석하였다. 두 단계 자원 제어에서 도착율 120 까지는 병행형과 순차형의 완료율이 100%를 달성하였으며, 병행형의 제어지연이 순차형에 비하여 약 21.5% 개선되었음을 확인하였다.
Abstract
Next generation network (NGN) is a packet-based converged network to support session and non-session services in QoS-enabled broadband transport network. QoS based resource control must be defined to support differentiated services for various network users in NGN. This paper defined parallel control schemes for NGN resource control interfaces to minimize session and resource control delays. We simulated the existing and proposed NGN control schemes to measure and analyze control delays and completion ratios. By arrival rate of 120 in two-phase resource control, we checked out that completion ratios of sequential and parallel schemes achieved 100%, and the control delay of parallel scheme was improved by about 21.5% compared to that of sequential scheme.
