ABSTRACT:
A method and apparatus for confirming delivery of files from a hub server to multiple receiving sites in a file broadcast system. Confirmation is assured in a file broadcast system, even where receiving sites are linked to a hub server via a connectionless network, by requiring receiving sites to delay transmission of confirmation by an amount of time which is different for each receiving site, by having the hub server aggregate multiple confirmations into a single acknowledgment message, and by requiring each receiving site to retransmit a confirmation if an acknowledgment message is not received from the hub server within a timeout period.
