본 논문은 리눅스를 내장하며, 다양한 인터페이스와 서비스 어플리케이션을 갖는 홈게이트웨이 시스템에서 리얼타임 서비스를 보장하며, 각 서비스 클래스에 대한 공정성을 보장하는 동적 우선순위 큐잉에 관한 연구이다. 기존의 리눅스에서는 동일한 우선순위를 부여함으로써 리얼타임 서비스에 대한 보장을 지원하지 못한다. 또한 리얼타임 서비스에 정적인 우선순위를 부여한다면 비리얼타임 서비스의 지연이 크게 되거나 서비스를 받지 못하는 기아현상이 발생한다. 본 논문에서는 일반 리눅스 커널에 리얼타임 리눅스 커널을 포팅하고, 리얼타임 커널에 큐잉엔진을 구현한다. 큐잉엔진은 동적 우선순위를 부여하고 리얼타임 스케줄러에 의해 처리되도록 함으로써, 리얼타임 서비스을 보장하고, 비리얼타임 서비스의 기아현상을 제거하며, 각 응용 서비스 클래스에 대한 서비스 공정성을 보장함으로써, 홈게이트웨이 시스템의 성능을 향상 시킨다.
