Hi NANOG,
>From August 24 to October 4, the University of Washington and Georgia Tech
will conduct an Internet routing study using AS-PATH poisoning. The study
will *only* affect the Georgia Tech experimental prefix
184.164.224.0/19(and its sub-prefixes). The prefix serves *no active
users/services* so the
study should not affect any production prefixes or users. We plan to insert
AS numbers into our announcements to route around some networks. We will
always start AS-PATHs with our own ASN 47065. We will limit ourselves to at
most 10 announcement changes per hour (and generally will change the
announcement for a given sub-prefix at most every 90 minutes).
This experiment is almost identical to one that Georgia Tech conducted in
June and July without problems or complaints
(http://mailman.nanog.org/pipermail/nanog/2011-June/037527.html), so we do
not anticipate any issues. Others have done similar studies in the past
(e.g., Randy Bush et al.:

If, for any reason, you want us not to include your ASN in announcements for
our prefix, please opt-out at any time before August 24 at:
http://www.surveymonkey.com/s/9P2TD7T . A few ASes opted out of the
previous Georgia Tech study, and we will continue to honor those opt-outs.
Please feel free to contact me directly with any questions.
Cheers,
