Abstract

LA TRANSMISION DE MENSAJE EN CLAVE CON CIRCULACION ESTATICA SE EFECTUA EN PAQUETES CON PAQUETES LARGOS POR COMUNICACIONES VIRTUALES. EN UN MECANISMO DE COMUNICACION DE PAQUETES NO SE PUEDEN EXCLUIR FUNDAMENTALMENTE YA QUE SIMULTANEAMENTE LLEGAN DOS O VARIOS PAQUETES POR LINEAS DIFERENTES QUE SON ASIGNADOS A LAS MISMAS LINEAS. ESTAAN PREVISTOS ACUMULADORES DE TOPE EN EL QUE PUEDEN ESPERAR PAQUETES QUE NO PUEDEN TRANSMITIR. EL COSTE DE ALMACENAMIENTO NECESARIO SE REBAJA Y DEPENDE DE LA LONGITUD DEL PAQUETE DEL NUMERO DE LINEAS DE CIRCULACION, MODO DE CIRCULACION DE LA BUENA TRANSMISION DE TRANSPORTE. EN EL MECANISMO DE COMUNICACION DE PAQUETES CONOCIDO SE EMPLEA EL 80% DE CLIP PARA ESTE ACUMULADOR DENTRO DEL CAMPLO ACOPLADOR. CON ARREGLO AL INVENTO SE REUNEN DENTRO DE LA POSICION DE COMUNICACION UN NUMERO FIJO DE PAQUETES EN UN MARCO. LOS PAQUETES SE DIVIDEN EN PAQUETES LARGOS Y SE REPARTEN EN CUADROS INFERIORES. SE COMUNICAN SOBRE LA BASE DEL CUADRO INFERIOR EN TIEMPO MULTIPLEX SINCRONO. LA DEMANDA DE SITIO DEL ACUMULADOR EN EL CAMPO DE ACOPLAMIENTO SE REDUCE LA RELACION CUADRO-CUADRO INFERIOR. COMO ACUMULADOR ACTUA LA COMUNICACION MULTIPLEX DE TIEMPO SIN ACUMULACION INTERIOR.
