[re-ECN] FW: New Version Notification for draft-moncaster-congestion-exposure-problem-02

[<[e-mail]>]

I have posted an updated version taking into account comments I received over the past week or so. Apologies if I have missed any comments.

http://www.ietf.org/id/draft-moncaster-congestion-exposure-problem-02.txt

The big missing pieces still are: use cases (I have added a couple of sentences suggesting what the end result should look like) and security (which Bob is hoping to be able to do - meanwhile I added some rough notes that I hope are a start).

If anyone has anything to contribute before the ID deadline on Monday let me have it by 1200 GMT Monday and I will endeavour to add it...

Toby

A new version of I-D, draft-moncaster-congestion-exposure-problem-02.txt has been successfuly submitted by T Moncaster and posted to the IETF repository.

Filename:	 draft-moncaster-congestion-exposure-problem
Revision:	 02
Title:		 The Need for Congestion Exposure in the Internet
Creation_date:	 2009-10-23
WG ID:		 Independent Submission
Number_of_pages: 19

Abstract:
The success of the Internet is largely down to the ability to share
capacity amongst all users while avoiding congestion collapse.
However this relies on the cooperation of all end users to work
efficiently - even if everyone uses TCP, a minority of users can
command a large share of the network.  To mitigate the growth in this
problem over recent years, some ISPs have imposed various controls on
traffic using a range of proprietary approaches.  These controls set
ISPs in conflict with their customers and with some regulators.

The root of the problem lies in the fact the ISPs are unable to see
the most important information about the traffic - namely the amount
of congestion that traffic is going to cause in the network.  We
propose congestion exposure as a possible solution.  This allows
packets to carry an accurate prediction of the congestion they expect
to cause downstream.  This memo sets out the motivations for
congestion exposure and introduces a strawman protocol designed to
achieve congestion exposure.
