COMMENT:
----------------------------------------------------------------------

I would expect that this document also mentions the interaction with congestion
control, e.g. see RMCAT. All I can find is this, which seems very high level:
"3.1.7. Specifications providing integration with system and delivery
   layers should be developed."

Further the security consideration section is rather brief while it actually
does mention security requirements. In a requirement document I would have
expected that these requirements are clearly spelled out and explained, as well
as risks/attacks are discussed.

And why is section 4 in this document and not in draft-ietf-netvc-testing?

Another minor comment:
Sec 2: "for instance, wired channels are considerably more error-
   free than wireless channels and therefore require different QoS
   approaches."
I don't think this is generally true as most mobile networks repair losses on
the lower layers.
