The IESG has approved the following document: - 'WebRTC Forward Error Correction Requirements' (draft-ietf-rtcweb-fec-10.txt) as Proposed Standard
This document is the product of the Real-Time Communication in WEB-browsers Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Barry Leiba. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-rtcweb-fec/ Technical Summary In situations where packet loss is high or perfect media quality is essential, Forward Error Correction (FEC) can be used to proactively recover from packet losses. This specification provides guidance on which FEC mechanisms to use, and how to use them, for WebRTC implementations. Working Group Summary The working group support for the document was generally high. One issued was raised in working group last call regarding the effectiveness of the Opus internal FEC mechanism. The document currently states that it is RECOMMENDED for protection against individual packet loss and that other methods are needed for multi-packet protection. This mirrors text in RFC 6716 and accurately captures a limitation of the in-band FEC mechanism. The question of effectiveness is thus tightly tied to the loss pattern. While data on this was presented, there was no evident consensus to update the requirement, so the recommendation from RFC 6716 was retained. Document Quality This document appears to have the support of the relevant development community and will likely be implemented and deployed. Reviews by Mo Zanaty, Magnus Westerlund, and Bernard Aboba were particularly helpful. Personnel Ted Hardie is the Document Shepherd. Adam Roach is the Responsible Area Director. _______________________________________________ IETF-Announce mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-announce
