서비스의 다양화와 함께 multicast 패킷의 비율이 증가하고 이를 전달하는 네트워크 시스템에서는 multicast 패킷의 스위칭 효율로 인하여 스위칭 효율이 감소하게 되어 시스템의 처리율 및 패킷의 서비스가 지연된다. 본 논문에서는 multicast 패킷의 스위칭 효율을 높여 패킷의 서비스 지연을 줄이기 위한 스위치 시스템 구조 및 패킷 버퍼링 구조, iSLIP을 이용한 새로운 패킷 스케쥴링(Scheduling)방법을 제안하였다. 제안된 스위치 시스템의 구조 및 스케쥴링 방법은 패킷의 스위칭 지연 관점에서 지금까지 제안된 multicast 패킷의 스위칭 바업들과 비교 시뮬레이션을 통하여 제안된 알고리즘의 성능을 검증하였다.
