[re-ECN] Pls bash: Congestion Exposure (re-ECN) BoF in Hiroshima?

[Bob Briscoe <[e-mail]>]

Hi Folks,

I'd like to try to arrange a Congestion Exposure (re-ECN) BoF in Nov 
at the Hiroshima IETF. Pls bash the following proposals.

A/ Basic idea: Expose Congestion at network layer, so operators can 
encourage endpoint behaviours that minimise congestion while 
maximising performance (e.g. LEDBAT).

B/ Which Area?
I suggest we should notify Int Area & Transport Area, but I imagine 
Transport Area would own this.

C/ Community (see separate mail)

D/ Ultimate documents to deliver (draft charter milestones):...?
1. (INF) Motivating cases for congestion exposure
2. (EXP) protocol spec (re-ECN is one proposal)
    - choosing an encoding in IP, plus alternative encodings in an appendix
3. <if the encoding uses bit 48 in IPv4>
    (STD) Reassign value 1 of bit 48 from 'reserved' to 'experimental use'
    Also describe conditions on experiments, e.g.:
    - confined in space and in time
    - multiple simultaneous experiments with same value would need v 
strong case
4. (INF) Report(s) on experimental uses of protocols

E/ Supporting text to work on
- BoF Description     (by 07 Sep 09 BoF deadline - Monday!!)
- Proposed BoF Agenda (by 28 Oct 09 WG agendas deadline)
- Problem statement   (by 19 Oct 09 I-D deadline)
- Protocol proposal(s) (by 19 Oct 09 I-D deadline)
- have I missed anything?

F/ Other requirements
- What's the "elevator pitch"?
- Demo? Of what? The protocol, or a use of the protocol? What use?
- BoF Chairs x2 (Rich Woundy has volunteered)
