Hi Julien,
In order to get a "good enough" result instead of getting an optimal result
in the dynamic scenario,
we have mentioned a possible procedure in the last paragraph of section 7.2
from the current version of the draft,
where the transit PCEs should be configurable to control the number of paths
sent upstream.
Then the challenge is to find the right number (or the "good enough" number)
of path sent upstream we can configure at the transit PCEs.
It depends on a lot of factors, such as the network topology and the
definition of the "good enough". :-)
Any suggestions regarding to procedures/heuristics that might help to get a
"good enough" number are welcome.
Thanks for your time!
Quintin

Hi.
Chair hat off, so non-authoritative answer. :-)
I tend to agree that "good enough" is enough, especially with respect to
an expensive optimality which might not be my fellow's optimality...
Thanks,
Julien
