Abstract
LA INVENCION SE REFIERE A UN METODO PARA PAQUETES DE CONMUTACION, QUE SON TRANSFERIBLES MEDIANTE PILAS DE TRANSMISION Y TIENE UN CODIGO DE CONTROL, EN UN SISTEMA DE CONMUTACION QUE TIENE VARIAS ENTRADAS Y VARIAS SALIDAS, DESDE LA ENTRADA EN QUE APARECE EL PAQUETE A UNA SALIDA ESPECIFICA DERIVADA DEL CODIGO DE CONTROL DEL PAQUETE. LA INVENCION HACE QUE LOS PAQUETES QUE APARECEN EN LAS ENTRADAS SEAN ALIMENTADOS, POR MEDIO DE UNOS PRIMEROS CANALES DE TRANSMISION QUE CONTIENEN PRIMERAS PILAS DE TRANSMISION, A UNOS SEGUNDOS CANALES DE TRANSMISION, QUE CONTIENEN LAS SEGUNDAS PILAS DE TRANSMISION, QUE CONDUCEN A LAS SALIDAS DEL SISTEMA DE CONMUTACION, UN PAQUETE DE ESTE TIPO TRANSFERIDO POR UNA PRIMERA PILA DE TRANSMISION SIENDO SIEMPRE TRANSMITIDO A LA SIGUIENTE PILA DE TRANSMISION SECUENCIAL, QUE NO ESTA YA OCUPADA POR OTRO PAQUETE, DE ESE SEGUNDO CANAL DE TRANSMISION QUE CONDUCE A LA SALIDA ESPECIFICA DERIVADA DEL CODIGO DE CONTROL.
