Hi Dirk and others,

[Speaking only for myself below, but along the lines of why I am
 willing to co-chair the propsed RG.]

The broadening of the scope beyond HOPS was intentional.
I too am interested in focused work, and we intend to have individual
items be focused, but from a RG perspective, something broad enough
to accept yet-to-be proposed topics was desired; so that the RG
can span multiple efforts potentially without rechartering, i.e.,
administrative work.

No, neither tools nor infrastructure (are inherently in scope),
but rather measurement techniques and discovery of how the Internet
exists and is "playing out" in ways that directly affect IETF goals
re: standards and BCP.

The charter as proposed specifically mentions towards advancing
(only) protocol design and operation.

> - are we planning to discuss middlebox issues?

Yes. We expect to transition this and continue this effort from the
non-RG-forming HOPS meetings, to the degree that there are people
to do the work.

In my mind, the effect iddlebox's have on protocol performance is
the "poster child" topic for our proposed MAP RG; if successful,
it will demonstrate how discovering substrate characteristics can
inform protocol development and operation/practice.

> - do we want offer discussion platform for general measurement topics?

No. There are other forums for that, e.g., the IPPM Working Group and
the Internet Measurement Conference.

Building measurement infrastructures, e.g., databases, is also
something we currently consider out of scope.

It might help if I offer some example topics (that Brian or I considered
as strawmen) that I find would be in scope:

- A survey of the IPv6 WWW, to inform practice with respect to privacy,
  e.g. service address assignment, virtual hosting, and SNI.
  Basically, "Are we building an IPv6 web that we want?"

- Large scale examination of IPv4 address utilization or "churn",
  and how it's changing in cooperation with IPv6.

- For operational purposes such as DoS mitigation, how should
  "IP reputation" likely need to change for IPv6.
  What needs to be measured (differently)?

These are use (semi-imaginary) examples, but I know of researchers
working on each of these that might benefit from bringing them to
an IRTF forum such as the proposed MAP RG.

> Please enlighten me. :-)

You be the judge. If you find that the charter doesn't jibe with
my comments above, please offer your suggested change(s).

Thanks Dirk!

Dave
