Abstract

Un método para multidifusion de una celda ATM, caracterizado porque comprende los pasos de: recibir la celda ATM en el primer puerto de entrada de un conmutador desde una red ATM; almacenar la celda ATM en un ciclo de reloj en un arreglo de memoria del conmutador; leer la celda ATM en el arreglo de memoria en un ciclo de reloj; transmitir la celda ATM desde el conmutador a la red ATM; leer nuevamente la celda ATM en el arreglo de memoria en un ciclo de reloj; y transmitir nuevamente la celda ATM desde el conmutador a la red ATM.
