WebApr 1, 2024 · Forward Error Correction (FEC) is a mechanism to recover lost packets on a link by sending extra “parity” packets for every group (N) of packets. As long as the receiver receives a subset of packets in the group (at-least N-1) and the parity packet, up to a single lost packet in the group can be recovered.
