WebForward Error Correction (FEC) is used to control and correct errors in data transmission by sending redundant data across the VPN in anticipation of dropped packets occurring during transit. The mechanism sends out x number of redundant packets for every y number of base packets. WebFeb 12, 2024 · Forward Error Correction (FEC) is a mechanism to recover lost packets on a link by sending extra “parity” packets for every group of 4 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. nestle bentonville ar office
