<html> <head> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> </head> <body text="#000000" bgcolor="#FFFFFF"> Hi, We will soon be resuming our measurements using the RIPE Atlas platform. We've scheduled the traceroutes to one every 18 seconds (a more uniform distribution than the previous approach of batches of 100 tests every 30 minutes), to address the concerns regarding the load we put on the system. We still have about 1,300 target addresses to test, so the total duration of the measurements is estimated to approx. 7 hours (i.e., scheduled to start at 16h00 CET -- with expected finishing time at around 23h00 CET). We do apologize for any inconvenience! For any further comments, inquiries, suggestions etc., do not hesitate to contact us! Thank you, best regards, Andra <div class="moz-cite-prefix">On 08/26/2013 10:23 AM, Andra Lutu wrote: </div> <blockquote cite="mid:521B1085.4070907@imdea.org" type="cite"> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> Dear all, The culprit for the high number of tests running on the RIPE Atlas platform would be me. I do apologize for not sending a notification prior to deploying the tests, we do understand that we are looking at quite a massive number of measurements. We are currently trying to slow down the rhythm of the traceroutes, in an effort to not be so aggressive. The purpose of the measurements is to establish the reachability of the limited-visibility IPv6 prefixes we were able to identify using the BGP Visibility Scanner. The measurements are a part of our efforts of enhancing our understanding on the results of the visibility tool for IPv6 prefixes. The RIPE Atlas team was kind enough to help us with our research and allowed us to use the Atlas platform. For more information about the BGP Visibility project, I kindly refer you to <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <a moz-do-not-send="true" href="http://visibility.it.uc3m.es/">http://visibility.it.uc3m.es/</a> We've previously focused on the visibility of the IPv4 prefixes, please find a more detailed view on our results in the following RIPE Labs article: <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <a moz-do-not-send="true" href="https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner">https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner</a> For any further inquiries, do not hesitate to contact us!
