ABSTRACT:
One embodiment of the present invention provides a system for distributing files across a network. During operation, the system receives a request at a server to download a file to a client. If the server is not currently downloading the file, the system commences a download stream for the file on a multicast port. If the server is currently downloading the file, the system remembers a marked location on the file, wherein the marked location relates to a current packet number of the download stream on the multicast port. The system then continues downloading the file until the end of the file, thereby allowing the client to receive the remainder of the file. Next, the system downloads the file from the beginning of the file to the marked location, thereby allowing the client to receive previously transmitted portions of the file.
