Invited talk, note the unusual room (CS 102). Please let me know if you would like to meet with Morley Mao while she is here. Speaker: Professor Morley Mao, U. Michigan Title: Effective Diagnosis of Routing Disruptions from End Systems Date/time: 1:30-2:30pm Friday December 5 Room: 102 in the CS building
Abstract: Internet routing events are known to introduce severe disruption to application performance. So far effective diagnosis of routing events has relied on proprietary ISP data feeds, resulting in limited ISP-centric views not easily accessible by customers or other ISPs. In this work, we propose a novel approach to diagnosing significant routing events associated with any large networks from the perspective of end systems. Our approach is based on scalable, collaborative probing launched from end systems and does not require proprietary data from ISPs. Using a greedy scheme for event correlation and root cause inference, we can diagnose both interdomain and intradomain routing events. Unlike existing methods based on passive route monitoring, our approach is able to measure the impact of routing events on end-to-end network performance as well. We demonstrate the effectiveness of our approach by studying five large ISPs over more than three and half months. We validate the accuracy of our approach by comparing with the existing ISP-centric method and with events reported on NANOG mailing lists. Our work is the first to scalably and accurately diagnose routing events associated with large networks purely from end systems.
