Hi Jack:<br>
<br>
Some quick answers.<br>

<br>
</div>The answer depends on whether you are trying to measure stuff on the current<br>
Internet or trying to innovate new protocols for the Internet. If you are<br>
measuring in the current network, measurements are done much as they always<br>
have been, by instrumenting boxes and end systems. The challenge is that<br>
fewer folks have open access to the boxes and end systems and access is<br>
often limited by confidentiality agreements. This sometimes leads to<br>
situations where a researcher has access to a valuable data set but doesn't<br>
know what questions to ask of it (i.e. right data, wrong researcher).<br>
<br>
Most of this kind of measurement work is published at the Internet Measurement<br>
Conference.<br>
<br>
If you are trying to innovate new protocols, the community has developed<br>
some large-scale test infrastructure: PlanetLab is an example, as is GENI.<br>
Some of these infrastructures allow you to run repeatable experiments, others<br>
do not.<br>
<br>

<br>
You'd have to narrow the question -- the volume of what has been learned<br>
is large. And we'd probably search for the answer in the IMC proceedings.<br>
<br>
Thanks!<br>
