We have uploaded an Internet-Draft called "Pre-congestion notification in mobile networks" - http://www.ietf.org/id/draft-jobert-tsvwg-pre-congest-notif-mobile-00.pdf
Mobile networks may be divided into two main segments: the radio
segment, and the wireline segment. This document highlights that the
algorithms leading to pre-congestion notification (e.g. ECN marking)
are usually significantly different for these two segments, and not
defined or documented in general over the radio segment. It also
explains that using ECN bits leads to having a unique signal for
notifying a pre-congestion related to two separate segments with
very different notification algorithms. Some consequences are
questioned, as well as the potential benefits of being able to
identify where the congestion comes from. This document finally
discusses the possibility to take into account the radio conditions
of the terminals when counting the volume of congestion over the
It has been posted in TSVWG, but the chairs indicated some possible interest from ICCRG.
We are interested by review and comments.
