Low Density Parity Check (LDPC) Forward Error Correction (draft-ietf-rmt-bb-fec-ldpc-01.txt)

This document describes two Fully-Specified FEC Schemes, LDPC-Staircase and LDPC-Triangle, and their application to the reliable delivery of objects on packet erasure channels. These systematic FEC codes belong to the well known class of ``Low Density Parity Check'' (LDPC) codes, and are large block FEC codes in these sense of RFC3453.
