Re: [re-ECN] Fwd: Pls respond: Do we have a Congestion Exposure community?

[Aaron Falk <[e-mail]>]

Hi Folks-

I see I've missed the deadline for this note.  Sorry, I've been on
vacation...

FWIW, I think re-ECN is a cool, albeit unproven, idea and further
development and experimentation will help build understanding of the
benefits and missing pieces.  This work seems like a very good fit for
R&D at the intersection of the research, standardization, and operations
community.  IETF meetings are about as close as one can get, although
getting the right folks into the room takes work and shouldn't be
assumed.  One possible, useful outcome of a re-ECN BoF could be an
effort around developing an experimental protocol and encouraging
limited deployments, as the HIP advocates have done.

I regret that I do not have the cycles to actively participate so
consider this standing on the sidelines and nudging.  :)

cheers,

ps.  I'm also thinking that "future Internet" research infrastructure,
like GENI, could provide instrumented, controlled -- and, over the next
few years, at-scale -- environments for  re-ECN (and other congestion
control) experiments but I don't think that is really a factor in the
BoF decision just a matter of my personal interest.
