It's irrelevant what application RSVP-TE fits in.  RSVP-TE and CR-LDP
do the same thing in slightly different ways.

In an ideal world, CR-LDP as an extension of LDP would have been
the way to go.  It's funny that you should be arguing on the other
side now -- let's do NTIP (read RSVP-TE) instead of LMP-WDM (read
CR-LDP) which is just an extension of LMP (read LDP) which nobody
needs anyway (read "TE is the only MPLS app").  Such is life ...

Guilty as charged.  We gave them black model Ts, and they liked them.
They didn't ask for any other colors, and aren't asking now, apart
from idle curiosity.

All the ISP folks that I know who had to make a choice say that
the process of choosing is mostly non-technical, and very much a
big pain.

The data I have indicates that the market wants competing
implementations of the same standard, not competing standards.
That's where the real value of "best of breed" lies.
