This document describes a fully specified simple Forward Error
Correction (FEC) scheme for Low-Density Parity Check (LDPC) Staircase
codes that can be used to protect media streams along the lines
defined by FECFRAME.  These codes have many interesting properties:
they are systematic codes, they perform close to ideal codes in many
use-cases, and they also feature very high encoding and decoding
throughputs.  LDPC-Staircase codes are therefore a good solution to
protect a single high bitrate source flow or to protect globally
several mid-rate flows within a single FECFRAME instance.  They are
also a good solution whenever the processing load of a software
encoder or decoder must be kept to a minimum.

This document is a product of the FEC Framework Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
