Abstract
UNA RED DE COMUNICACIONES TIENE UNA ARQUITECTURA DE BUS BIDIRECCIONAL Y FLEXIBLE (FBDNA), Y SE DISPONE COMO UNA ESTRUCTURA EN ANILLO. CADA NODO DE LA RED TIENE, AL MENOS, UN CONMUTADOR DE NODO DE PERMISO/BLOQUEO, ES DECIR, UN CONMUTADOR QUE PERMITE O BLOQUEA LA TRANSMISION ALREDEDOR DE LO QUE, EN OTRAS PALABRAS, SERIA UN ANILLO. SI LA RED TIENE UN CONMUTADOR DE NODO POR NODO, SE ESTABLECE UN CONMUTADOR DEL NODO COMO BLOQUEADO PARA EVITAR LOS PROBLEMAS CON LA EMISION ESPONTANEA AMPLIFICADA DE CIRCULANTE (ASE) QUE ESTA NORMALMENTE ASOCIADA CON UNA ESTRUCTURA EN ANILLO. SI OCURRE UNA ROTURA DE LA FIBRA, EL CONMUTADOR DEL NODO (O LOS CONMUTADORES DE LOS NODOS) EN EL NODO (O EN LOS NODOS) CONTIGUOS A LA ROTURA Y EN EL MISMO LADO DEL NODO QUE LA ROTURA, CONMUTA A LA POSICION DE BLOQUEO, Y EL NODO QUE ESTABA BLOQUEADO ANTES DE LA ROTURA, CONMUTA A LA POSICION DE PERMISO, PERMITIENDO QUE LA RED FUNCIONE, EN GRAN PARTE, COMO ANTES. SI LA RED TIENE DOS CONMUTADORES DE NODO POR NODO, LOS DOS CONMUTADORES DE NODO SIGUIENTES A LOS CORRESPONDIENTES DE LOS NODOS VECINOS, SE ESTABLECEN INICIALMENTE COMO BLOQUEADOS, Y SI OCURRE UNA ROTURA DEL CABLE, AMBOS CONMUTADORES DE NODO EN EL AREA DE LA ROTURA, CONMUTAN A LA POSICION DE BLOQUEO, Y EL CONMUTADOR DE NODO QUE ESTABA INICIALMENTE BLOQUEADO, CONMUTA A LA POSICION DE PERMISO. LA RED PROPORCIONA UNA CONMUTACION PROTECTORA DEL TRAFICO, Y RESUELVA EL PROBLEMA DE LA ASE CIRCULANTE DE UNA FORMA SIMPLE Y ECONOMICA. LA RED TAMBIEN PERMITE LA RECONFIGURACION DE LA LONGITUD DE ONDA PARA REDUCIR EL NUMERO DE LAS LONGITUDES DE ONDA REQUERIDAS.
