Abstract

Métodos y nodo capaces de establecer ponderaciones de enlace basadas en el factor de protección vinculado con el nivel de protección de una pluralidad de enlaces entre un nodo fuente y un nodo de destino y capaces de establecer propuestas de la ruta primaria, y potencialmente, de la ruta de protección usando las ponderaciones de enlaces establecidas. Se determina un valor del ancho de banda disponible para el enlace. Si el valor del ancho de banda para el enlace es mayor que el requerimiento del ancho de banda asociado con la ruta potencial, entonces la ponderación de enlace para el enlace se establece calculando un factor de protección asociado con el enlace con el valor de ancho de banda disponible para el enlace. De lo contrario, la ponderación de enlace para el enlace se establece en un valor que indica que el enlace no deber ser parte de la ruta potencial. Se podría aplicar el algoritmo de la ruta más corta para obtener las propuestas de las rutas, usando las ponderaciones de enlace establecidas.
