Good question. I think we're now at the point where publishing analysis of
Internet measurement data is no longer a novelty. So, the bar should
naturally get higher for what consistitutes "research" in this area -- work
that lends new/deep insight into the behavior of a system or protocol, or
work that adds new methods and techniques to our bag of tricks. (Also, I
think students are in a position now where doing an entire PhD thesis on
collecting and characterizing measurement data might not be "enough". They
might reasonably need to use the insights from the data analysis to redesign
a system, create new algorithms, etc. That is, measurement and data
analysis might be a phase in the work, rather than the entire body of the
work.)
Also, I would argue that the body of existing work has grown so large (and
so quickly) that it is getting hard for new people to jump in to the area,
and existing folks to keep up with what's going on. (Henk alluded to this
problem as well, in commenting on how many different venues have a
significant emphasis on Internet measurement. Actually, even putting
together a simple Web site that linked to the main venues would be a useful
contribution at this point!)
In terms of the important question of "who needs the information," I think
we have at least two camps -- those using data to characterize the beast
(e.g., research folks trying to do experimental science on the Internet,
including work on understanding the performance and limitations of our
existing protocols and/or evaluate new designs) and those using data to run
the network (e.g., operators trying to detect anomalies, do traffic
engineering, thwart attacks, etc.), though increasingly the lines are blurry
as more research folks jump in to creating and evaluating techniques for
using measurement data to help operators.

Mark - my reflections would parallel Jennifer's - measurement has
matured to a certain point and I feel that it is time for it to make
itself relevant to other things - integrate with the larger world and/or
be part of other systems that need measurement. In other words, can we
get down to applied research?
Jennifer listed some options to consider.
A key question (in my mind) is: Now that we know better how to do it,
what is Internet Measurement good for? Or more precisely, who needs
that information and under what circumstances?
My experience as an industry researcher has been that the answer to this
question is non-trivial and not what you'd expect. For example, in
general I would say that core network engineers "don't care" - however,
applications people (who have little direct access to the network) care
a great deal but in specific ways and under specific circumstances.

Mark,
Hi, thanks for getting the ball rolling. Here are a few thoughts to
give
the ball an additional kick. I'm not sure which of these (if any) make
sense specifically in a context like IMRG, but these are some
measurement-related things I've been thinking or wondering about...
- Education/curriculum:
- Network support for measurement:
- Measurement in support of network operations:
