Abstract

간단한 회로로 에러 전파를 억제한다. 패킷 선두 검출 회로(22)는 전송 패킷의 선두를 검출하여 검출 신호를 패킷화 회로(21)에 부여한다. 패킷화 회로(21)는 검출 신호가 주어지고, N'개의 기록 패킷 단위로 n'개의 전송 패킷을 순차적으로 배열하여 패킷화한다. 이것에 의해 N'개의 기록 패킷의 선두가 배치된다. 예약 데이타 삽입회로(24)는 예약 데이타를 결합회로(23)에 부여하고, 결합 회로(23)는 전송 패킷이 배열되어 있지 않은 기록 패킷의 부분에 예약 데이타를 삽입하여 출력한다. 이것에 의해 에러가 발생했을 경우에도 기록 패킷을 구별하는 것으로 전송 패킷을 식별할 수 있어서 에러의 전파를 억제할 수 있다.
