Abstract

EL MEDIO LOGICO DE ENCAMINAMIENTO RL SELECCIONA PRIMERO, EN BASE A UN NUMERO DE REFERENCIA DE RUTA INCLUIDO EN LA ETIQUETA DE ENCAMINAMIENTO INTERNA (TCA, TCP) Y ASOCIADO A LA CELULA A ENCAMINAR POR ESTE, AL MENOS UN CONJUNTO QUE INCLUYE UN NUMERO DE GRUPOS DE ENCAMINAMIENTO CADA UNO DE LOS CUALES INCLUYE UN NUMERO DE SALIDAS. EL MEDIO LOGICO DE ENCAMINAMIENTO SELECCIONA ENTONCES DE FORMA SECUNDARIA UN GRUPO DE ENCAMINAMIENTO POR CONJUNTO SELECCIONADO DE GRUPOS DE ENCAMINAMIENTO Y FINALMENTE SELECCIONA TAMBIEN DE CADA UNO DE TALES GRUPOS DE ENCAMINAMIENTO UNA SALIDA A LA CUAL SE TRANSFIERE UNA COPIA DE LA CELULA ANTES MENCIONADA. DE ESTA FORMA UNA DISTRIBUCION DE (COPIAS DE) CELULAS HASTA LOS PUERTOS DE SALIDA ARBITRARIAMENTE ESCOGIDOS DE UN NODO DE CONMUTACION QUE INCLUYA DICHO MEDIO LOGICO DE ENCAMINAMIENTO PUEDE SER AFECTADA TANTO POR CONEXIONES PUNTO A PUNTO COMO POR CONEXIONES MULTIEMISION. EN UNA REALIZACION PARTICULAR, LA PRIMERA SELECCION SE HACE POR MEDIO DE UNA MEMORIA DE ENCAMINAMIENTO (RM) CUYAS UBICACIONES DE MEMORIA (MSK) SE DIRECCIONAN VIA EL NUMERO DE REFERENCIA DE LA RUTA. EL CONTENIDO DE ESTA UBICACION DE MEMORIA SE INTERPRETA ENTONCES MEDIANTE UN MEDIO DE SELECCION (SEL) QUE IDENTIFICA LOS GRUPOS DE ENCAMINAMIENTOS INCLUIDOS EN EL CONJUNTO Y REALIZA LA SEGUNDA SELECCION DE MODO ALEATORIO SELECCIONANDO CUALQUIERA DE LOS GRUPOS INCLUIDOS EN EL CONJUNTO.
