David, I respect your approach, letting us know about your bandwidth study and what each network operator can expect. The important part is that we get the opportunity to either opt-out, or find out a way to "opt-in" and help you acquire more information to complete your research. Too bad Digital Isle didn't follow the same approach. Regards, Christopher J. Wolff, CTO Broadband Laboratories ---------- Original Message ---------------------------------- From: "David G.

Given the current thread about unwanted network probe traffic, I figured it would be a good idea to pre-announce this and let people have a chance to put their netblocks on a deny list in advance, if they so desire.
(Note: We'd really appreciate it if you'd let our probes go through! It's an important part of some of the research we're doing).
We're running some traceroutes and pings to observe the end-to-end reachability of sites around the times of BGP route changes. This means that if you have a stable network, you probably won't see too many probes from us, but if you flap all the time, you'll see up to a few probes per hour. (One probe == one traceroute).
The probes are extremely low-bandwidth and as non-invasive as we can make them, but if you'd like to be put on an exclusion list for this and any other probing experiments our research group runs, please send mail to:
mon-request@nms.lcs.mit.edu
Include all of the netblocks that you'd like excluded, preferably like:
18.31.0.0/24
Thanks,
-Dave Andersen
