Abstract
멀티캐스트 ATM(Asynchronous Transfer Mode) 교환기(switch) 및 그 멀티캐스트 경합 조정(Multicast Contention Resolution) 방법 및 장치가 기재되어 있다. 본 발명에 따른 멀티캐스트 ATM 교환기는 셀 복제와 셀 어드레싱을 동시에 수행한다. 셀 복제는 인입 셀들을 라우트 및 소팅 모듈 모두에 브로드캐스트시킴으로써 이루어진다. 셀 라우팅과 경합 기능은 라우트 및 소팅 모듈 내의 스위치 소자 어레이에 의해 분산 수행된다. 라우팅 링크를 공유하는 개념(통상, 채널 그룹화라 불림)이 하드웨어의 복잡도를 줄이기 위해 전체 교환기 구조를 구현하는데 적용된다. 본 발명에 따른 입력 포트 제어기는 입력 포트에 도달한 셀들을 종단시키고 버퍼링하여 번역 테이블에서 필요한 라우팅 정보를 찾아 셀들 앞에 붙여 다수의 라우트 및 소팅 모듈을 포함하는 멀티캐스트 그룹-소팅 네트워크로 전송한다. 이 입력 포트 제어기는 멀티캐스트 그룹-소팅 네트워크로부터 궤환되는 정보를 가지고 멀티캐스트 패턴을 변경함으로써 멀티캐스트 경합 조정을 수행한다.
