A forward error correction system comprising a first device which a) processes a number (N) bytes within each of a plurality of original packets to form a respective forward error correction code of M bytes, b) processes a number (P) of the original packets to form Q additional error correction packets each associated with respective forward error corrections code, and c) transmits said P original packets and said Q additional forward error correction packets as a stream of data as well as their respective forward error correction codes; and a second device which receives the data stream and which a) processes the data stream to correct errors in a received corrupted packet as a function of the respective forward error correction code; b) responsive to errors which cannot be so corrected, processes such errors as a function of the Q additional forward error correction packets to correct said error; and c) responsive to failing to correct such errors, returns a message indicative of said failure and includes in the message a request to expand said forward error correction processing at said first device.
