Deduction of TWCs and Internal Wavelengths Needed for a Design of Asynchronous OPS System with Shared or Output FDL Buffer

광 패킷 스위칭은 미래 광 인터넷을 위한 스위칭 기술로 고려되고 있다. 광 패킷 스위칭 내부의 경합 해결을 위해 파장 변환 기법이 광 지연 선로 버퍼와 함께 일반적으로 사용되어 진다. 본 논문에서는 공유형 혹은 아웃풋 광 지연 선로 버퍼를 갖는 비동기 광 패킷 스위칭 시스템의 비용 효율적인 설계를 위해 가변 파장 변환기를 공유함으로써 필요한 파장변환기 개수의 감소를 도출한다. 비동기 가변길이 패킷들을 비용 효율적 설계를 위해 고려하였고, 그러한 광 패킷 스위칭 시스템 내부에 필요한 가변 파장 변환기 개수를 도출하기 위해 출력 단의 채널뿐아니라 유용 가능한 가변 파장 변환기와 내부 파장 또한 찾아 주는 스케쥴링 알고리즘을 제안한다. 제안된 알고리즘을 공유형 혹은 아웃풋 광 지연 선로 버퍼를 갖는 비동기 광 패킷 스위칭 시스템에 적용하여 비용 효율적 설계를 위해 필요한 가변 파장 변환기 및 내부 파장 개수를 도출하였다.
