Abstract

Un sistema para actualizar objetos en una red entre un aparato local y uno remoto, que comprende:un modo de computarizar una primera función de huella en cada desviación de byte de un primer objeto en el aparato remoto, un modo para hacer chunking al primer objeto del aparato remoto basado en la primera función de huella; un modo de computarizar una firma remota para cada chunk asociado con el primer objeto en el aparato remoto;un modo para generar una firma y lista de longitud de chunk remota en el aparato remoto, donde la firma y la lista de Iongitud de chunk remotas están asociadas con el primer objeto; un modo para computarizar una segunda función de huella en cada desviación de byte de un segundo objeto en el aparato local, donde el primero y segundo objetos están asociados uno con el otro y donde la primera función de huella concuerda con la segunda función de huella; un modo para hacer chunking en el segundo objeto en el aparato local basado en la segunda función de huella, donde la manera para hacer chunking del primer objeto en el aparato remoto concuerda con la manera para hacer chunking en el segundo objeto en el aparato local;un modo para computarizar una firma local para cada chunk asociado con el segundo objeto en el aparato local, donde la manera para computarizar la firma local concuerda con la manera para computarizar la firma remota;un modo para generar una firma local y una lista de longitud de chunk en el aparato local, donde la firma y la lista de longitud de chunk local están asociadas con el segundo objeto;un modo de negociar una transmisión de chunk de la firma remota y lista de longitud de chunk del aparato remoto al local a través de la red de tal forma que el uso del ancho de banda se minimiza para la transferencia de la firma y lista de longitud de chunk remota al aparato local; un modo para identificar las diferencias entre el primer objeto y el segundo, comparando la firma y la lista de longitud de chunk local a la firma y lista de longitud local remota en el aparato local;un modo para solicitar la transmisión de por lo menos un objeto actualizado del aparato remoto cuando las diferencias entre el primer objeto y el segundo son identificados por el aparato local; un modo de transmitir por lo menos un chunk del objeto actualizado del aparato remoto al local a través de la red;un modo para re-ensamblar una copia del primer objeto en el aparato local con, por lo menos; un chunk de objeto actualizado.
