Title (EN) TRANSMISSION AND ROUTING OF OPTICAL SIGNALS
(FR) TRANSMISSION ET ROUTAGE DE SIGNAUX OPTIQUES
Abstract:
(EN) Methods and apparatus for routing and transmission of inverse multiplexed signals over optical communications networks are described. A method for routing includes determining a plurality of paths for transmission of a plurality of inverse-multiplexed optical signals from a source node to a destination node of an optical network. Each path is for transmission of at least one of the inverse-multiplexed optical signals. A latency difference between a fastest one of said paths and a slowest one of said paths is less than a predetermined time period.
(FR) Cette invention concerne des procédés et un appareil de routage et de transmission de signaux inverses multiplexés par des réseaux de communication optique. Un procédé de routage consiste à déterminer plusieurs voies de transmission de plusieurs signaux optiques inverses multiplexés provenant d'un nœud source vers un nœud de destination d'un réseau optique. Chaque voie sert à la transmission d'au moins un des signaux optiques inverses multiplexés. Une variation de latence entre l'une des voies les plus rapides et l'une des voies les plus lentes est inférieure à un délai prédéfini.
