Low Density Parity Check Staircase and Triangle Forward Error Correction Schemes

Overview

RFC 5170, “Low Density Parity Check Staircase and Triangle Forward Error Correction Schemes”, is a Proposed Standard document published in June 2008 by V. Roca, C. Neumann, D. Furodet. The canonical text is published by the RFC Editor.

Abstract

This document describes two Fully-Specified Forward Error Correction (FEC) Schemes, Low Density Parity Check (LDPC) Staircase and LDPC Triangle, and their application to the reliable delivery of data objects on the packet erasure channel (i.e., a communication path where packets are either received without any corruption or discarded during transmission). These systematic FEC codes belong to the well- known class of "Low Density Parity Check" codes, and are large block FEC codes in the sense of RFC 3453. [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
