Hi Will,

 

here are some brief comments on the above draft for your consideration:

 

Technical Changes

Page 8:

   (1) policy relies on and is able to adjust service

<jcs> policy manages and can adjust service behavior as necessary </jcs>


   (2) policy relies on network ability provided by resource and is
   able to adjust resource

<jcs> policy manages and can adjust resource behavior as necessary </jcs>

 

   (3) resource relies on network ability and is able to reserve and
   consume/occupy resource

<jcs> resource hosts service; changing resources may change service behavior as necessary </jcs>

 

Page 10

 

(1)=>(2)=>(3)=>(4)=>(3')=>(2')=>(1')

 

   Where, (1)=GPIM; (2)=EPRIM; (3)=YANG data models; (4)=
   Implementation; (3')= update of YANG data models; (2')=update of
   EPRIM; (1') = update of GPIM

 

   The YANG module derived from the GPIM contains concepts and
   terminology for the common operation and administration of policy-
   based systems, as well as an extensible structure for policy rules
   of different paradigms. The YANG module derived from the EPRIM
   extends the generic nature of the GPIM to represent policies using
   an event-condition-action structure.

 

<jcs>

I suggest the following additional text:

   The above sequence allows for the addition of new, as well as editing

   of existing, model elements in the GPIM and EPRIM. In practice, the

   implementation sequence may be much simpler. Specifically, it is

   unlikely that the GPIM will need to be changed. In addition, changes

   to the EPRIM will likely be focused on fine-tuning the behavior

   offered by a specific set of model elements.

</jcs>

 

NITS!

Please update [SUPA-info-model] to point to draft-ietf-supa-generic-policy-info-model-01

Should we update [] to point to draft-ietf-netmod-rfc6020bis-14

 

Pages 3-4

I offer to redraw the figure, there are lines that are past the character limit
