Hi all,

 

We have uploaded an Internet-Draft called = “Pre-congestion notification in mobile networks” - http://www.ietf.org/id/draft-jobert-tsvwg-pre-congest-notif-mob= ile-00.pdf

 

Abstract

 

   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

   radio = segment.

 

It has been posted in TSVWG, but some aspects discussed in = this draft are related to discussions in CONEX, and might be of interest = to the WG.

We are interested by review and = comments.

 

Thanks.
