CA 2090429
An arrangement of coupled hybrid rings is disclosed which can withstand a failed node or a cut ring in either or both the hybrid rings, as well as an outage of one of the two serving nodes utilized to interconnect the hybrid rings. The pair of serving nodes are interposed in each of the hybrid rings and serve to transmit signals between the two rings to satisfy the hybrid ring requirement of having equivalent signals propagating in two opposing directions on the unidirectional rings composing an individual hybrid ring.
Système d'anneaux hybrides couplés (301 et 302) qui peuvent supporter un noeud en dérangement ou un anneau coupé dans un des anneaux hybrides ou dans les deux, ainsi qu'une défaillance d'un des deux noeuds de desserte utilisés pour relier les anneaux hybrides. La paire de noeuds de desserte (330 et 340) est interposée dans chaque anneau hybride et elle sert à transmettre des signaux entre les deux anneaux pour que l'anneau hybride ait effectivement des signaux équivalents se propageant dans deux direction opposées (par exemple, 311 et 312) sur les anneaux unidirectionnels formant un anneau hybride individuel.
