Abstract

UN SISTEMA DE COMUNICACIONES ATM QUE TIENE UN DBA, Y QUE COMPRENDE UNA MEMORIA PARA EL TRAFICO DBA, CUYA MEMORIA INCLUYE UNA MEMORIA DEDICADA PARA EL TRAFICO ABR, Y EL SISTEMA ES TAL QUE LAS SOLICITUDES DE ANCHO DE BANDA ABR SON ASIGNADAS UNA VEZ QUE EL RESTO DE LAS ASIGNACIONES DE ANCHO DE BANDA DBA HAN SIDO SATISFECHAS, Y HAY UNOS ELEMENTOS PARA INTERRUMPIR UNA TRANSMISION ABR, ANTES DE QUE UNA ASIGNACION DE ANCHO DE BANDA DENTRO DE LA CUAL SE INCLUYE DICHA TRANSMISION ABR SE HAYA UTILIZADO TOTALMENTE PARA LA TRANSMISION DE OTRO TRAFICO DBA DE MAYOR PRIORIDAD.
