Abstract

En una red de telecomunicaciones que tiene una pluralidad de nodos inteligentes (101-106) interconectados por multiples canales de comunicacion (121-128), se definen trayectorias alternas y canales disponbiles (151-158) para restaurar el tráfico interrumpido por la falla de uno o más de los canales de comunicaciones. Las trayectorias alternas pueden definirse sin consideracion al numero de pares de nodos custodios, también referidos como pares guía/seguidor o emisor/selector, que podrían involucrarse simultáneamente en la operacion de restauracion. Los nodos interconectados (101-106) tienen funcionamiento bidireccional y/o canales disponibles (131-138 y 151-158). En cada nodo en la red que participa en la operacion de recuperacion, se almacena una manifestacion de canal disponible para cada una de las comunicaciones guí/seguidor.
