Steve,

Isn't it the case that the only reason that ITU-T (or
OIF for that matter) considers RSVP-TE and CR-LDP because
they're both approved standards from IETF? In other
words, the ITU-T and OIF merely adapt (or adopt)
"existing" protocols for the IP-based control plane.
If IETF decides to stop progressing one of these protocols
further, wouldn't it lighten the (redundant) work
that goes on in the ITU-T? I also don't see why there
ought to be a joint decision between ITU-T and IETF
on this. Given that the ITU-T is at
a stage where the protocol work is still evolving
and no deployment is at stake, it makes good sense to
welcome the move from the IETF to clarify the
signaling protocol picture.
