Abstract
LA INVENCION SE REFIERE A UN SISTEMA CONMUTADOR ATDM QUE CONSTA DE UN CONVERTIDOR DE SERIE A PARALELO (100) COLOCADO PARA RECIBIR PAQUETES DE DATOS ENTRANTES (QUE CONTIENEN SU PROPIA INFORMACION DE ENCAMINAMIENTO) DESDE VARIOS PUESTOS (107) EN FORMATO SERIE Y LLEVARLES, EN FORMATO PARALELO, A UNA MEMORIA DE ACCESO ALEATORIO (RAM) (101, 102) DE TAL MANERA QUE LOS PAQUETES FORMAN COLAS DENTRO DE LA MEMORIA, UNA PARA CADA PUERTO DE SALIDA. LOS PAQUETES SON ENTONCES TRANSFERIDOS EN FORMATO PARALELO, UNO PARA CADA COLA EN TURNO, A UN CONVERTIDOR DE SERIE A PARALELO (105) QUE LOS LLEVA A SUS PUESTOS DE SALIDA CORRESPONDIENTES (109) EN FORMATO SERIE. LA COLOCACION ES TAL QUE CUANDO LA MEMORIA SE LLENA EL SISTEMA PUEDE ACOMODAR LOS PAQUETES SOBREESCRIBIENDO LOS DATOS QUE HAY EN LA COLA MAS LARGA, UNA TECNICA QUE PUEDE REDUCIR SIGNIFICATIVAMENTE EL NUMERO TOTAL DE PAQUETES PERDIDOS DURANTE UNA OPERACION A LARGO PLAZO.
