Abstract
본 논문에서는 labeled optical burst switching (LOBS) 네트워크의 제어 패킷의 정보를 나타내는 레이블(label)중에 고속 처리가 필요한 정보를 RF 캐리어로 표시하여 고속의 버스프 스위칭을 가능케 하는 레이블 코딩 방식과 OBS 노드의 재어 방식을 제안하였다. 재안된 레이블 코딩 에서는 중간 노드에서 실시간 처리를 필요후 히는 경료 라우팅과 QoS 지원 등과 같이 패킷 처리의 우선순위를 나타내는 레이블을 수 개의 RF 캐리어와 그들의 물리적인 파라미터로 표현하였다. 이로써, 중간 노드에서 레이블 처리시간을 현격히 줄일 수 있으므로 옵셋타임의 감소를 가져오고 결과적으검 빠른 버스드 교환을 가능케 한다 제안된 레이블 코딩 방식을 적용한 OBS 시스템의 제어 방식과 시스템 구조를 제시하였고 시뮬레이션과 실험을 통해 구현된 제아 패킷의 형상을 보임으쿄써 제안한 방 식의 효용정을 입증하였다.
