Data files are transmitted by receiving requests from destination devices for the files and dividing the files into first and second subsets where the files of the second subset are associated with one file of the first subset. The files of the second subset are compressed using one of the files in the first subset as a reference. The compressed files are divided into packets. A portion of the compressed files of the second subset, and a portion of the files of the first subset is cached.

Abstract
Data files are transmitted by receiving requests from destination devices for the files and dividing the files into first and second subsets where the files of the second subset are associated with one file of the first subset. The files of the second subset are compressed using one of the files in the first subset as a reference. The compressed files are divided into packets. A portion of the compressed files of the second subset, and a portion of the files of the first subset is cached. Un-cached portions of respective files from the first subset are transmitted to destination devices that have requested these files, and un-cached portions of one particular file from the second subset, and un-cached portions of files in the first subset that are associated with the one particular file, are transmitted to respective destination devices that have requested the particular file from the second subset.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
