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. This document describes some considerations
relating to the use of IP protocol number fields and payload protocol
(e.g. TCP) port fields in protocols and deployed services. The IAB would
like to ensure that the IETF community has had an opportunity to
read it and comment before its publication.
The IAB solicits comments by July 7, 2003. Please send
comments to the IAB (iab@iab.org), or to ietf@ietf.org.
The document can be found at

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.
