Hey all, As a follow-up to Mikael's point in AOB at the MAT meeting today (that there are lots of statistics already being kept by hosts, e.g., in TCP stacks): I did a presentation at the IEPG back at the Beijing IETF about the idea of standardizing a "Network Measurement Reporting" language, so that things like ping and traceroute could share their results with the rest of the Internet. <http://iepg.org/2010-11-ietf79/NMR-IEPG.pdf> It's long enough ago that I don't remember precisely what the feedback was. But no further work got done, so it probably wasn't that positive :) Nonetheless, I continue to think that collecting ambient measurement data is a really interesting idea, so it would be cool to hear what others here think. Cheers, --Richard
