Forward Error Correction Framework Extension to Sliding Window Codes

Overview

RFC 8680, “Forward Error Correction Framework Extension to Sliding Window Codes”, is a Proposed Standard document published in January 2020 by V. Roca, A. Begen. It updates RFC 6363. The canonical text is published by the RFC Editor.

Abstract

RFC 6363 describes a framework for using Forward Error Correction (FEC) codes to provide protection against packet loss. The framework supports applying FEC to arbitrary packet flows over unreliable transport and is primarily intended for real-time, or streaming, media. However, FECFRAME as per RFC 6363 is restricted to block FEC codes. This document updates RFC 6363 to support FEC codes based on a sliding encoding window, in addition to block FEC codes, in a backward-compatible way. During multicast/broadcast real-time content delivery, the use of sliding window codes significantly improves robustness in harsh environments, with less repair traffic and lower FEC-related added latency.

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.
