Abstract

Una red de telecomunicaciones opticas tiene una pluralidad de conexiones cruzadas opticas que conmutan los nodos unidos mediante cables opticos para formar las trayectorias de transmision para el tráfico entre las estaciones emisoras y de destino. Un sistema de soporte de operacion centralizada (OSS) se acopla a cada nodo para recibir alarmas de falla y mensajes del estado del puerto por los cables que fallan desde los nodos de conmutacion y los sitios terminales. Los datos recolectados se utilizan para seleccionar las rutas alternas a través de la red utilizando la capacidad de reserva de las conmutaciones opticas de conexion cruzada y las longitudes de onda disponibles dentro de la red. Cualquier conexion(es) para poner en efecto un plan de ruta alternativo, se difunde hacia los nodos afectados o los sitios terminales. Se utiliza un algoritmo de Encaminamiento de Longitud de Onda Multiple de Tiempo Real (RMWR) mediante el OSS o por nodos de conmutacion descentralizados para seleccionar, coordinar y encaminar el tráfico entre las trayectorias seleccionadas para derivar el cable de falla, de tal manera que las colisiones de longitud de onda o perturbaciones adyacentes no degraden el desempeño de la red. El OSS se actualiza cuando se lleva a cabo la restauracion de la red mediante un nodo de conmutacion en la trayectoria de cable de falla.
