본 논문에서는 이더넷 패킷에 대한 서비스 품질을 보장할 수 있는 통합전달 시스템을 설계 및 구현하였다. 구현된 통합전달 시스템은 하나의 장치에서 MPLS 기반의 L2 VPN 서비스, 프리미엄 멀티미디어 서비스 및 TDM 전용회선 서비스를 동시에 제공할 수 있다. 제안된 통합전달 시스템은 VCG로 구성된 채널별로 QoS 정책을 설정하고 그 용량을 제어할 수 있기 때문에 기존의 이더넷 시스템에서는 가질 수 없었던 높은 신뢰성을 제공할 수 있어 고 품질 실시간 서비스 제공이 가능하다. 구현된 시스템의 성능 실험은 3노드로 구성된 링 네트워크에서 성공적으로 수행되었다.
