The IAB chair is evidently suffering from a few too many cold medicines, and did an abysmal job on editing a previous message to suit the current needs. Sigh. With apologies, and appreciation to those who are reading these announcements and caught my mistake :-) what I wanted to say was... The IAB is ready to ask the RFC-Editor to publish IAB Concerns Regarding Congestion Control for Voice Traffic in the Internet draft-iab-congestion-01.txt as an Informational RFC. The IAB solicits comments by November 14, 2003. Please send comments to the IAB (iab@iab.org), or to ietf@ietf.org. The document can be found at http://www.ietf.org/internet-drafts/draft-iab-congestion-01.txt From the Abstract This document discusses IAB concerns about effective end-to-end congestion control for best-effort voice traffic in the Internet. These concerns have to do with fairness, user quality, and with the dangers of congestion collapse. The concerns are particularly relevant in light of the absence of a widespread QoS deployment in the Internet, and the likelihood that this situation will not change much in the near term. This document is not making any recommendations about deployment paths for VoIP in terms of QoS support, and is not claiming that best-effort service can be relied upon to give acceptable performance for VoIP. We are merely observing that voice traffic is occasionally deployed as best-effort traffic over some links in the Internet, that we expect this occasional deployment to continue, and that we have concerns about the lack of effective end-to-end congestion control for this best- effort voice traffic.
