Methods and apparatus are provided for N+1 packet level mesh protection. An error correction encoding method is provided that assembles M-T data packets; appends a sequence number and a payload integrity check to each of the M-T data packets; and creates T protection packets having the sequence number and payload integrity check, wherein a payload for each of the T protection packets are formed from corresponding symbols in the M-T data packets. An error correction decoding method is also provided that receives a plurality of error-free packets and one or more packets having an error; and reconstructs the one or more packets having an error by applying block erasure decoding to said plurality of error-free packets, whereby one packet having an error can be reconstructed for each protection packet used to encode the received packets.
