Abstract

EN UNA RED (ATMN) DE COMUNICACION ORIENTADA CON CELDAS SE ENCAJAN EN DOS PARED (EP, AP) DE VIAS REDUNDANTES A TRAVES DE CORRIENTE DE CELDAS DE MENSAJES TRANSMITIDOS DE FORMA RESPECTIVA CELDAS DE CONTROL EN DISTANCIA DE TIEMPO PREVIAMENTE DETERMINADA. LAS CELDAS DE CONTROL CONTIENEN RESPECTIVAMENTE NUMEROS DE SUCESION QUE CAMBIAN DE FORMA CONTINUA DESDE UNA CELDA DE CONTROL A OTRA CELDA DE CONTROL. EN EL EXTREMO DE LOS PARES DE VIA SE SUPERVISA LA APARICION DE LAS CELDAS DE CONTROL ESPECIALMENTE PARA AMBAS CORRIENTE DE CELDAS DE MENSAJE. CON ELLO SE DETERMINA PRIMERO LOS NUMEROS DE SUCESION QUE APARECEN EN LA CORRIENTE DE CELDAS DE MENSAJE, QUE SE ADELANTAN EN AMBAS CORRIENTES DE CELDAS DE MENSAJE. LA CORRIENTE DE CELDAS DE MENSAJE ADELANTADA SE RETARDA ENTONCES HASTA LA APARICION DE IGUALES NUMEROS DE SUCESION EN LA CORRIENTE DE CELDAS DE MENSAJE.
