Abstract

UN METODO, APARATO Y PROGRAMA DE ORDENADOR PARA REDUCIR LOS DATOS TRANSMITIDOS POR UN ENLACE DE COMUNICACION EXTERNO (35) DESDE UNA PRIMERA APLICACION (20) RESIDENTE EN UN PRIMER ORDENADOR (6) HASTA UNA SEGUNDA APLICACION (10) RESIDENTE EN UN SEGUNDO ORDENADOR (5). EL METODO, APARATO Y PROGRAMA DE ORDENADOR INCLUYEN EL ALMACENAMIENTO DE UN FLUJO DE DATOS DESDE LA PRIMERA APLICACION PARA SER PROPORCIONADOS A LA SEGUNDA APLICACION EN RESPUESTA A UNA PETICION DE LA SEGUNDA APLICACION EN UNA CACHE RESIDENTE EN EL PRIMER ORDENADOR PARA CREAR UNA ENTRADA DE CACHE DE BASE DEL SERVIDOR Y EN UNA CACHE RESIDENTE EN EL SEGUNDO ORDENADOR PARA CREAR UNA ENTRADA DE CACHE DE BASE DEL CLIENTE. LAS PETICIONES DE LA SEGUNDA APLICACION SE INTERROGAN PARA DETERMINAR SI EXISTE UNA ENTRADA DE CACHE DE BASE DEL CLIENTE CORRESPONDIENTE A LA PETICION INTERROGADA Y DETERMINAR SI EXISTE UNA ENTRADA DE CACHE DE BASE DEL SERVIDOR CORRESPONDIENTE A LA INTERROGADA. SE INTERCEPTA EL FLUJO DE DATOS DE RESPUESTA ANTES DE LATRANSMISION DE LA RESPUESTA POR EL ENLACE DE COMUNICACION EXTERNO Y SE COMPARA A LA ENTRADA DE LA CACHE DE BASE DEL SERVIDOR PARA PROPORCIONAR LOS DATOS DE LA DIFERENCIA CORRESPONDIENTE A LA DIFERENCIA ENTRE LA RESPUESTA INTERCEPTADA Y LA ENTRADA DE LA CACHE DE BASE DEL SERVIDOR. LOS DATOS DE LA DIFERENCIA SE ENVIAN POR EL ENLACE DE COMUNICACION EXTERNO (35) Y LOS CONSIGUE EL SEGUNDO ORDENADOR EL CUAL RECONSTRUYE EL FLUJO DE DATOS DE RESPUESTA COMBINANDO LA ENTRADA DE LA CACHE DE BASE DEL CLIENTE CON LOS DATOS DE DIFERENCIA PARA CREAR UN FLUJO DE DATOS DE RESPUESTA QUE SE PROPORCIONA A LA SEGUNDA APLICACION.
