[re-ECN] Revised agenda theory

[Leslie Daigle <[e-mail]>]

Hi,

We need to get an agenda posted.  Subject to suggested changes, and/or 
absent howls of dissent, we'll post the following. Note that I have 
expanded it to allow more discussion of the specific viability of the 
approach.

We'll work on framing up some discussion for that part of the agenda 
during the next week, or so.

Leslie.



Congestion Exposure (ConEx) is a proposed new IETF activity to enable
congestion to be exposed along the forwarding path of the Internet. By
revealing expected congestion in the IP header of every packet,
congestion exposure provides a generic network capability which allows
greater freedom over how capacity is shared. Such information could be
used for many purposes, including congestion policing, accountability
and inter-domain SLAs. It may also open new approaches to QoS and
traffic engineering.

The purpose of the BoF is to explore the support for and viability of
pursuing an IETF activity to define a basic protocol to expose the
expected rest-of-path congestion in the IP header. Any such protocol
should work with minimal changes to the existing network, in particular
it should work with unmodified routers. There is already one existing
proposal that builds on ECN to provide rest-of-path congestion
information in every IP header and other proposals may come forward.

Agenda

  5 mins  administrivia
  5 mins  introduction by chairs
40 mins  the problem
             context/motivation [Rich Woundy]
             technical problem [Mark Handley]
10 mins  constraints  [Philip Eardley]
30 mins  towards a solution
             overview of re-ECN   [Bob Briscoe]

N.B.:  This assumes our current 160min agenda space (check my math!). If 
the BoF moves, we'll have to re-think.
