Abstract

NGN is a packet-based converged network to support session and non-session based services in QoS-enabled broadband transport technologies. Resource and admission control functions(RACF) of NGN have been considering COPS and SNMP as resource management protocols to collect network topology and resource status information of transport network. This paper defines requirements of resource management in NGN transport network, and proposes protocol independent information model to keep consistency of data models of each resource management protocol. Based on this information model described with UML class diagram, we designed and implemented NGN resource management system on Web Services.

NGN은 QoS가 지원되는 광 대역 전달 망에서 세션 및 비-세션 서비스를 지원하기 위한 패킷 기반의 융합 망이다. NGN의 RACF(Resource and Admission Control Functions)는 전송망의 토폴로지 및 자일 상태 정보곤 수집하기 위하여 COPS와 SNMP를 자원 관리 프로토콜로 고려하고 있다. 본 논문에서는 NGN 전송 층의 토폴로지 및 자원 상태 관리를 위한 요구 사항을 정의하며 자원 제어 프로토콜에서 정의되는 데이터 모델들의 일관성을 유지하기 위해 프로토콜 중립적인 정보 모델을 제안한다. 또한, UML로 기술된 정보 모델을 이용하여 웹 서비스 기반의 NGN 자원 관리 시스템을 선계 및 구현하였다.
