Abstract

본 발명은 고속화와 대용량에 적합한 출력버퍼형 ATM 스위치 구조에 관한 것으로, 특히 스위치의 입력단을 통해 동시에 들어오는 N개의 셀을 출력단 그룹에 따라 작은 것에서 큰 순으로 배열하는 배처-솔팅(Batcher-sorting) 네트워크(BSN)(401); 상기 배처-솔팅 네트워크(BSN)(401)에서 배열된 셀을 각각의 출력단이 속하는 출력단 그룹으로 출력하는 확장형 반얀(Banyan) 네트워크(EBRN)(402); 및 상기 확장용 반얀 네트워크(EBRN)(402)로부터 출력되는 셀을 공동 메모리인 버퍼에 일시 저장한 후, 출력단으로 송출하는 출려단 버퍼수단(OQM:Output Queueing Modules)(403)을 구비하여, 여러 입력셀을 각 출력단으로 동시에 송출할 수 있는 분산처리가 가능하고, 모듈화로 인하여 구현이 용이하며, 각 입출력단으로 입출력되는 고속의 데이타를 스위치의 속도배율(speed-up) 없이도 처리할 수 있다.
