Abstract: A device receives a packet, of multiple packets, relating to a file being delivered via multicast, and a file delivery table associated with the file. The file delivery table includes uniform resource identifiers corresponding to respective sources of the file. The device determines that one or more portions of the file, that are included in the packet, are in need of repair after receiving the packet. The device provides, to a respective source corresponding to a uniform resource identifier, a request for data relating to the one or more portions of the file based on determining that the one or more portions of the file are in need of repair, receives the data from the respective source based on the request, and processes the data to repair the one or more portions of the file while one or more other packets of the multiple packets are being received.
