Technical Summary
This document describes two fully-specified Forward Erasure
Correction (FEC) Schemes for Sliding Window Random Linear Codes
(RLC), one for RLC over GF(2) (binary case), a second one for RLC
over GF(2^^8), with the possibility of controlling the code density.
They can protect arbitrary media streams along the lines defined by
FECFRAME extended to sliding window FEC codes. These sliding window
FEC codes rely on an encoding window that slides over the source
symbols, generating new repair symbols whenever needed. Compared to
block FEC codes, these sliding window FEC codes offer key advantages
with real-time flows in terms of reduced FEC-related latency while
often providing improved packet erasure recovery capabilities.
Working Group Summary
This document is a companion to draft-ietf-tsvwg-fecframe-ext,
which is an update to the FECFRAME work in RFC 6363. RFC
6363 was a product of the former FECFRAME working group,
which closed several years ago. FECFRAME was in the TSV area.
When several original FECFRAME participants proposed
updates/extensions to support new types of codes (with benefits for
some real world applications), between the Area Directors and
TSVWG, it was agreed that the work should be done in TSVWG,
and two documents including this one were adopted. Several
FECFRAME participants are either authors/editors listed on the
documents, or participated in reviews. Other than this history,
there were no other significant issues or events of interest in the
working group process on this document.
Document Quality
There have been implementations. The implementations were
reported to the working group, and the documents benefited
from the implementation and testing experience.
Personnel
The document shepherd is Wesley Eddy (wes@mti-systems.com),
and the responsible AD is Magnus Westerlund.
