Title: YANG Models for Quality of Service (QoS) in IP networks
Reviewer: Zaheduzzaman Sarker
Review result: Ready with Nits

The draft defines a set of YANG models for managing Quality of Service (QoS) in
IP networks, particularly those based on DiffServ (Differentiated Services).

It didn't flag anything particular to INTAREA.

That said, I have some comments which I believe will add more clarity to the
document if addressed -

* It says -

        The DSCP markings are applied by upstream node or by the edge router on
        entry to the DiffServ network.

Does this mean PHB according to the DSCP marking is applied? if yes, can we say
that?

>> I have modified the wording to below text:

"The DSCP markings are applied by upstream node or by the edge router on entry 
to the DiffServ network. The traffic streams are differentiated based on 
DiffServ Code Points (DSCP) carried in the IP header of each packet and 
per-hop-behavior according to the DSCP marking is applied."

* Please consult with the RFC-editor's Abbreviations list for the well known
abbreviations which probably do not need expansion in the section 1.3.

>> Sure, I will follow up.

* Section 2: the figure has "Target", can it be clear that it means Target? It
can be interface or policy, right?

>>  The below text can be found at the end of section 2:

"The target is assumed to be interface but the groupings can be used for any 
other target type where QoS policy is applied."

* Section 3:
        - If classifier does not provide filters, where do we get them from for
        the " grouping filters”?

>> classifier is part of the base framework. "grouping filters" is provided by 
>> diffserv model.
