Abstract

EN UNA RED DE CONMUTACION CON UNA PLURALIDAD DE ENTRADAS Y SALIDAS Y UNA PLURALIDAD DE NUDOS DE CONMUTACION INTERCONECTADOS QUE TIENEN ENTRADAS Y SALIDAS CON RESPECTIVAS DIRECCIONES, SE DESCRIBE UN METODO DE MODIFICACION DE UN PRIMER JUEGO DE SALIDAS A LAS QUE SE ENCAMINA UNA CORRIENTE DE CELULAS DE UNA DE LAS ENTRADAS A UN SEGUNDO JUEGO DE SALIDAS A LAS QUE ESTA CORRIENTE DE CELULAS HA DE ENCAMINARSE, LAS DIRECCIONES DE LAS SALIDAS DE CADA NUDO DE CONMUTACION DEL CUAL LA CORRIENTE SALE SE ALMACENA EN UNA TABLA DE ENCAMINAMIENTO DEL NUDO. EL METODO COMPRENDE LOS PASOS DE: - TRANSMITIR UN MENSAJE DE PETICION DE MODIFICACION A LAS ENTRADAS A PARTIR DE CADA SALIDA QUE PERTENECE A UNO PERO NO A AMBOS JUEGOS, - EN CADA NUDO DE CONMUTACION QUE RECIBE EL MENSAJE DE SOLICITUD DE MODIFICACION SOBRE UNO DE SUS SALIDAS, TRANSMITIR SELECTIVAMENTE EL MENSAJE DE PETICION A LAS ENTRADAS O TRANSMITIR UN MENSAJE DE CONFIRMACION A CADA SALIDA ANTERIOR DEPENDIENDO DE LA AUSENCIA O PRESENCIA EN LA TABLA DE ENCAMINAMIENTO DE NUDO DE DIRECCIONES DE SALIDAS DE NUDO DISTINTAS DE LA SALIDA DE NUDO UNO, RESPECTIVAMENTE.
