Hi Tom,



Thanks. I think there is still some inconsistency as you pointed out. Please see inline. This should be it. I uploaded v.14 that incorporated all your comments. Attached is the new version notification and the below is the pointer for the diff.

https://www6.ietf.org/rfcdiff/?url2=draft-lee-teas-actn-pm-telemetry-autonomics-14



Please let me know if any further fix is needed.



Best regards,



Young

I remain confused.  What I see is



s.1.3



      | te-kpi  | ietf-te-kpi-telemetry        | [This I-D]      |

      | vn-tel  | ietf-vn-kpi-telemetry        | [This I-D]      |



YL>> te-kpi should be te-tel



YANG Modules



  namespace "urn:ietf:params:xml:ns:yang:ietf-te-kpi-telemetry";

  prefix te-tel;



  namespace "urn:ietf:params:xml:ns:yang:ietf-vn-kpi-telemetry";

  prefix vn-tel;



YL>> This is now consistent with s.1.3





IANA Considerations



   URI: urn:ietf:params:xml:ns:yang:ietf-te-kpi-telemetry

   URI: urn:ietf:params:xml:ns:yang:ietf-kpi-telemetry



YL>> ietf-kpi-temetry should be ietf-vn-kpi-telemetry.



   namespace:    urn:ietf:params:xml:ns:yang:ietf-te-kpi-telemetry

   namespace:    urn:ietf:params:xml:ns:yang:ietf-vn-kpi-telemetry



Too many prefix, too many URI.



And IANA Considerations - which is authoritative so I tend to look at first - must specify prefix but it does not



YL>> Added: prefix: te-tel and prefix:vn-tel

   --------------------------------------------------------------------

   name:         ietf-te-kpi-telemetry

   namespace:    urn:ietf:params:xml:ns:yang:ietf-te-kpi-telemetry

A new version of I-D, draft-lee-teas-actn-pm-telemetry-autonomics-14.txt
has been successfully submitted by Young Lee and posted to the
IETF repository.

Abstract:
   This document provides YANG data models that describe performance
   monitoring telemetry and scaling intent mechanism for TE-tunnels and
   Virtual Networks (VN).

   The models presented in this draft allow customers to subscribe and
   monitor their key performance data of their interest on the level of
   TE-tunnel or VN. The models also provide customers with the ability
   to program autonomic scaling intent mechanism on the level of TE-
   tunnel as well as VN.






Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
