Abstract
A system, method, and storage medium provide dynamic, packet-based adaptive forward error correction over a lossy bidirectional data communication medium that couples a transmitting device to a receiving device. The transmitting device repeatedly transmits encoded data packets formed by applying, to unencoded data, a forward error correction (FEC) algorithm having a level N that indicates a number of correctable errors. The receiving device attempts to decode the encoded data packets using the FEC algorithm, requesting retransmission of a packet if there are too many errors to correct. The transmitting device decreases the level N when it does not receive such a request within a given duration. By contrast, the transmitting device increases the level N when it receives a sequence of such requests having a threshold length, each request being received less than the given duration after the previous request.
