Abstract

EN UNA RED LOCAL DE COMUNICACIONES CON NODULOS EN LOS QUE SE UTILIZA EL SISTEMA DE AUTORIZACIONES PARA DETERMINAR QUE ESTACION PUEDE TRANSMITIR, SE DESCRIBE UN SISTEMA QUE ASEGURA QUE LOS DATOS DE LA RED NO SE INVALIDAN INCLUSO CUANDO UN NODULO FALLIDO ES REACTIVADO. LA AUTORIZACION PASA ALREDEDOR DE LOS NODULOS Y SI UNO DE ESTOS FALLA, EL QUE LE SIGUE RECIBIRA POR DEFECTO LA AUTORIZACION CUANDO EL VALOR AL FINAL DEL INTERVALO DE RETARDO OBTENIDO DE LA LISTA DE AUTORIZACIONES SE CUENTA HACIA ATRAS HASTA CERO. LOS NODULOS FALLIDOS QUE SE ACTIVAN TENDRAN QUE ESPERAR UN TIEMPO INFINITO PARA RECIBIR UN MENSAJE, CONTENIENDO UN VALOR SIMBOLICO QUE REINICIA LA CUENTA ATRAS DEL NODULO RECIENTEMENTE ACTIVADO Y QUE DEVUELVE A ESTE A LA RED EN SU PROPIA SECUENCIA.
