The use of Forward Error Correction (FEC) codes is a classic solution to improve the reliability of unicast, multicast, and broadcast Content Delivery Protocols (CDPs) and applications [RFC3453]. "Forward Error Correction (FEC) Framework" [RFC6363] describes a generic framework to use FEC schemes with media delivery applications and, for instance, with real-time streaming media applications based on the RTP real-time protocol. Similarly, "Forward Error Correction (FEC) Building Block" [RFC5052] describes a generic framework to use FEC schemes with objects (e.g., files) delivery applications based on either the Asynchronous Layered Coding (ALC) [RFC5775] or the NACK- Oriented Reliable Multicast (NORM) [RFC5740] protocols.

Simple Low-Density Parity Check (LDPC) Staircase Forward Error Correction (FEC) Scheme for FECFRAME
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.
