Re: [Explicit-meas] Explicit Flow Measurements implementations

[Ian Swett <[e-mail]>]

Thanks for the summary.

Is there a plan to share(via email or presentation) what's been learned
from those experiments with the IETF?  If they've been shared in the past
and I forgot, please just add relevant links to this thread so they're easy
for people to find.

Thanks, Ian
