Title (EN) NON-BLOCKING COPY NETWORK FOR MULTICAST PACKET SWITCHING
(FR) RESEAU DE COPIE NON GROUPANT POUR COMMUTATION DE PAQUETS MULTIDESTINATAIRE
Abstract:
(EN) A copy network (3) capable of packet replication is disclosed. An encoding process transforms the set of copy numbers, specified in the headers of incoming packets, into a set of monotone address intervals which form new packet headers. This process is carried out by a running adder network (8) and a set of dummy address encoders (10). A broadcast banyan network (12) performs the packet replication according to a Boolean interval splitting algorithm. Finally, trunk number translators (14) determine the destinations of individual copies. The copy network is self-routing, non-blocking and has a constant packet latency.
(FR) Réseau (3) de copie capable de reproduire des paquets. Un procédé de codage transforme l'ensemble des nombres de copies, spécifié dans les en-têtes de paquets entrants, en un ensemble d'intervalles d'adresses monotones créant de nouveaux en-têtes de paquets. Ce procédé est exécuté par un réseau (8) additionneur de traitement, ainsi qu'un ensemble de codeurs (10) d'adresses fausses. Un réseau banyan (12) de diffusion effectue la reproduction du paquet selon un algorithme de coupure d'intervalle Booléen. Enfin des traducteurs (14) de numéros interurbains déterminent les destinations des copies individuelles. Le réseau de copie est à acheminement automatique, non groupant et a un temps d'attente de paquet constant.
