통신 환경이 변하면서, 기존의 서비스에 따라 크게 음성망과 패킷망으로 구분되던 망 구조가 하나의 통합된 망에서 모든 서비스를 제공하는 구조로 진화하고 있다. 그리고, 이러한 서비스를 가능하게 하는 기술로서 VoIP(Voice over IP)가 최근까지도 계속 각광받고 있다. 그러나, 많은 노력에도 불구하고, 음성서비스와 같은 실시간 서비스의 엄격한 품질 요구조건을 보장하는 문제 때문에 VoIP 기술의 실제 적용이 지연되고 있다. 이에 본 논문에서는 통합망의 패킷 전달망을 ACE2000 MPLS 시스템 기반의 MPLS 망으로 구축함으로써 음성서비스의 품질을 보장하는 망 구조를 제시하고자 한다. 아울러 TE Server를 이용해서, 음성호를 전달하는 ER-LSP(Explicit Routed Label Switched Path)를 설정하는 호 설정 절차를 제시하였다.
