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.: http://www.psg.com/~olaf/measurements/as3130/visibility.pdf<http://www.google.com/url?sa=D&q=http://www.psg.com/~olaf/measurements/as3130/visibility.pdf>). 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.
