Hi Dirk/Dave,

I had read it a while ago, and have just re-read it now.  Overall, a very nice draft and I support progressing it.

Just two suggestions for editorial clarification:

- "TCP/IP" is referred to in various sections, and then afterwards the "IP protocol stack" is mentioned once in section 3.2.  Wouldn't it be better to use "IP protocol stack" as the generic reference instead of "TCP/IP".  This is because one is never sure if by "TCP/IP" you also mean to include UDP or not?  And now with the rolling out of QUIC/HTTP (which is UDP based) this distinction becomes more important.  This can become a minor or major point of confusion depending on the reader's background.  I've gotten this feedback myself on other drafts that I have written.

- Is it wise to entitle section 7.7 as "Strawman principles for an ICN QoS architecture" since strawman usually has a negative implication ( ) ?

Hello ICNRG,

Dave has kindly updated the QoS Architecture Considerations draft, responding to earlier comments from Eve during IRSG review.

I was wondering what people think of this revision. Check out the diff to see the changes.

If we are generally happy with it, I'd like to pass it back to the IRSG on Monday, August 31st.

As a reminder, this is an individual submission, not a RG document as most of our RFCs-to-be. Still, any feedback would be appreciated, of course.
