본 논문은 10G G-PON(Gigabit passive optical network) 네트워크와 NGN(Next generation network) 연동 구조를 설계하고, 10G G-PON 연동 시 문제점 해결을 위한 동적 GEM(G-PON encapsulation mode) Port-ID 할당 방법을 제안했다. 동적GEM Port-ID 할당 방법은 OMCI(ONT management control and interface) 구조 설계를 통해 IP 주소와 포트 번호를 혼합한형태의 맵핑 구조를 갖는다. 이는 NGN이 요구하는 클래스 기반 QoS(Quality of service) 뿐만 아니라 트래픽 단위의 QoS 지원까지 가능한 구조로서, 기존 G-PON 네트워크를 NGN에 그대로 적용시킨 구조 보다 QoS 지원에 있어 30% 이상 성능을 향상 시킨다.
