A gateway apparatus (200) includes multiple network server cards (206N) which are synchronized with each other to allow time slot switching of synchronous data across an asynchronous medium between source and destination server cards. The gateway (200) includes synchronization logic and a data adaptation layer which implements a protocol for formatting of synchronous serial data. The data undergoes serial to parallel conversion and is formed into per time slot subpackets which are further packetized along with context and synchronization data. The packet is transmitted through an asynchronous switch after which the packet is disassembled into its constituent subpackets and queued into play-out buffers according to each subpackets' associated context and synchronization data. The apparatus (200) allows synchronous data to be switched from a source time slot to a destination time slot across the asynchronous switch with a known, fixed delay. The gateway apparatus (200) requires only a single asynchronous switch to transmit data between and among both the synchronous and asynchronous domains.

L'invention concerne un dispositif passerelle qui comprend plusieurs cartes de serveur de réseau synchronisées, ce qui permet d'assurer une commutation en intervalle temporel de données synchrones sur un support asynchrone entre des cartes de serveur d'origine et de destination. La passerelle comprend une logique de synchronisation et une couche d'adaptation de données à protocole de formatage des données synchrones série. Les données subissent une conversion série/parallèle, constituées en sous-paquets par intervalle de temps qui connaissent une mise en paquets ultérieure en liaison avec des données de contexte et de synchronisation. La transmission de paquet s'effectue via un commutateur asynchrone, puis le désassemblage de paquet donne des sous-paquets constitutifs avec mise en file d'attente sous la forme de tampons de restitution, selon les données de contexte et de synchronisation associées aux différents sous-paquets. Le dispositif permet la commutation de données synchrones depuis un intervalle de temps d'origine vers un intervalle de temps de destination via le commutateur asynchrone, moyennant un retard fixe connu. Ce dispositif nécessite un seul commutateur asynchrone pour la transmission de données entre les domaines synchrone et asynchrones.
