Abstract:
A method for validating that K packets of a file have been successfully received by a receiver out of N packets transmitted thereto by a transmitter, wherein the receiver deems each received packet as â€œgoodâ€  or â€œbadâ€ , said method comprising the steps of:determining whether at least (K+1) packets have been deemed â€œgoodâ€  by the receiver; if so, selecting a (K+1)th packet out of the at least (K+1) â€œgoodâ€  packets; reconstructing K original packets and a (K+1)thâ€² packet from K of the non-selected â€œgoodâ€  packets, the (K+1)thâ€² packet corresponding to the selected (K+1)th packet; and determining whether the selected (K+1)th packet and the reconstructed (K+1)thâ€² packet are identical, whereby the K non-selected â€œgoodâ€  packets, and thus the reconstructed K original packets, are validated if so.
