Raptor Forward Error Correction Scheme for Object Delivery

Overview

RFC 5053, “Raptor Forward Error Correction Scheme for Object Delivery”, is a Proposed Standard document published in October 2007 by M. Luby, A. Shokrollahi, M. Watson, T. Stockhammer. The canonical text is published by the RFC Editor.

Abstract

This document describes a Fully-Specified Forward Error Correction (FEC) scheme, corresponding to FEC Encoding ID 1, for the Raptor forward error correction code and its application to reliable delivery of data objects.

Raptor is a fountain code, i.e., as many encoding symbols as needed can be generated by the encoder on-the-fly from the source symbols of a source block of data. The decoder is able to recover the source block from any set of encoding symbols only slightly more in number than the number of source symbols.

The Raptor code described here is a systematic code, meaning that all the source symbols are among the encoding symbols that can be generated. [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.
