We present a new methodology to detect and localize events that affect interdomain routing.
While it is still based on the analysis of BGP updates collected at different monitoring points
like other previous works, every other aspect of the method is part of our contribution. First,
measuring both long and short term interdomain routing behavior, we point out key features in
interdomain routing stability and reachability. Then, we derive empirical criteria from these
characteristics to analyze each and every update (not only bursts) as they come along. Our
method is therefore free from any kind of arbitrary thresholds. What is more, the method has
been designed to throw an alarm as early as possible, once an event has been detected with
a succinct accuracy. We test our method, analyzing a month of updates collected by sixteen
routers in various ASs. Validation, which is somewhat tricky in interdomain root cause
analysis is realized upon outage tickets from a Tier1 AS.
Bio:
Mickael Meulle received a B.A. in Physics, a M.S. and Ph. D in Computer Science from the Blaise Pascal University, Clermont-Ferrand (France), in 2000, 2003 and 2007, respectively. Mickael also received an Engineer Diploma from Institut Supérieur d'Informatique et de Mathématique Appliquées, Clermont Ferrand (France) in 2003. The M.S. and Ph. D. thesis were pursued at Orange Labs, Issy-Les-Moulineaux (France) and are dealing with discovery of Internet topology, inference of Internet routing policies and Internet provider business relationships. Mickael became a member of CORE/CPN research staff at Orange Labs after completion of the Ph.D.
