CA 2439783

A communication system for the mutual interconnection of a plurality of lower traffic level (5 Terabit) switch nodes via a relatively higher traffic level (Petabit) connection bus, which system comprises in operative association with each node, a two part TDM optical data management interface, wherein a first of the two parts comprises a time slot resequencer which serves to provide for the transmission of data from its associated node to the bus, and wherein a second of the two parts comprises a time slot specific combiner which serves for the transmission of data from the bus to its associated node, each node and the bus having independent data scheduling.

L'invention concerne un système de communications destiné à l'interconnexion entre une pluralité de noeuds de commutation à faible charge de trafic (5 térabit) via un bus de connexion à charge de trafic relativement élevée (pétabit). Ce système comprend une association fonctionnelle à chaque noeud, ainsi qu'une interface de gestion de données optiques TDM en deux parties. La première partie comprend un séquenceur d'intervalles de temps qui permet de transmettre les données entre son noeud associé et le bus. La seconde partie comprend un mélangeur spécifique d'intervalles de temps qui permet de transmettre les données entre le bus et son noeud associé, chacun des noeuds et le bus présentant une programmation de données indépendante.
