Abstract

Per permettere di diffondere un pacchetto di dati da un ingresso (I1) verso più uscite (01, 02, 03, 06), la rete di connessione comprende, in ogni piano di commutazione, almeno uno stadio (S2) costituito da commutatori elementari (SE4, SE5, SE6) aventi almeno la capacità: - di instradare più esemplari di un pacchetto che è stato moltiplicato a monte (SE1);- di moltiplicare un pacchetto, riemettendolo più volte successivamente su una stessa uscita; gli esemplari così creati essendo instradati in seguito dai commutatori elementari (S67, SE8, SE9) di uno stadio (S3) situato a valle.La rete si applica ai centri di commutazione ATM fotonici.
