Erminio Hi,

I belong to an Operator, I strongly agree with Greg.

 

Regards

Medel

Dear Erminio,
even though I'm not an operator but I think that you've went bit too far
in your first generalization.
"Every generalization is wrong, including this one"

Greg

The technical concern raised during the WG poll has not been resolved so
the
history definetely matters.

Quoting RFC5921:

  There are thus two objectives for MPLS-TP:

  1.  To enable MPLS to be deployed in a transport network and operated
      in a similar manner to existing transport technologies.

  2.  To enable MPLS to support packet transport services with a
      similar degree of predictability to that found in existing
      transport networks.

Based on the extensive comments provided by transport operators and
ITU-T
community, the solution in this draft is useless in case 1.

The fact that the solution in this draft is not backward compatible with
existing IP/MPLS BFD implementations means that this solution is also
uselesee
in case 2.

Are there other undocumented use cases for MPLS-TP deployments?

Erminio,
I do not think the history is relevant for this specific discussion...
Also I find it inappropriate to give statements with no justifications
behind.
You say: "the solution in this draft is useless for many MPLS-TP
deployments.".  in order to seriously consider your comment, you have
to
show why it is useless and which requirements are not satisfied.
Otherwise you cannot expect anyone to refer to your point.
Best regards,
Nurit

P.s. did you mean that the document is useless to available
non-standard
deployments, e.g. T-MPLS?
