Hi Gorry,

Thanks for engaging.

If it was a never, then the sentence would be

  3.  AQM algorithm deployment MUST NOT require tuning of initial or
configuration parameters.

I believe that the "in common use case" is redundant (and somehow
confusing) with the SHOULD in your proposal.
SHOULD (RFC 2119):

    3. SHOULD   This word, or the adjective "RECOMMENDED", mean that
       may exist valid reasons in particular circumstances to ignore a
       particular item, but the full implications must be understood and
       carefully weighed before choosing a different course.

However, I don't want to be picky on that point. I'll let your
responsible AD decide.
My main point is covered. I'll clear that DISCUSS point.
> parameters in common use cases.
> 4.3 AQM algorithm deployment SHOULD NOT require tuning in common use
I don't see this change in the v10.
There is an important word in here: "deployment" as opposed to "deployed"
in the current 4.3 section title (4.3. AQM algorithms deployed SHOULD NOT
require operational tuning)
"Deployment" brings to the notion of initial deployment as opposed to
This is the reason why I propose:

4.3 AQM algorithm deployment SHOULD NOT require operational tuning

I hope you will include this change, but it's not DISCUSS-worth IMO.
Same remark as above regarding "AQM algorithm deployment"

Regards, Benoit
