SUMMARY:On Mapping the Interconnections in Today’s Internet
DESCRIPTION:Internet interconnections are the means by which networks
 exchange traffic between one another. These interconnections are typically
 established in facilities that have known geographic locations\, and are
 owned and operated by so-called colocation and interconnection service
 providers (e.g.\, Equinox\, CoreSite\, and EdgeConneX). These previously
 under-studied colocation facilities and the critical role they play in
 solving the notoriously difficult problem of obtaining a comprehensive view
 of the structure and evolution of the interconnections in today’s
 Internet are the focus of this talk.\n\nWe present mi2\, a new approach for
 mapping Internet interconnections inside a given colocation facility. We
 infer the existence of interconnections from localized traceroutes and use
 the Belief Propagation algorithm on a specially defined Markov Random Field
 graphical model to geolocate them to a target facility. We evaluate mi2 by
 applying it to a diverse set of US-based colocation facilities. In the
 process\, we compare our results against those obtained by two recently
 developed related techniques\, and discuss observed discrepancies that
 result from how the different techniques determine the ownership of
 (border) routers. We also report on drastic changes in today’s Internet
 interconnection ecosystem (e.g.\, new infrastructures in the form of cloud
 exchanges that offer new types of interconnections) and reflect upon their
 far-reaching implications for obtaining an accurate and comprehensive map
 of the Internet’s interconnections.\n\nThis is joint work with Reza
 Motamedi\, Bahador Yeganeh (University of Oregon)\, Balakrishnan
 Chandrasekaran (Technische Universität Berlin)\, Bruce M. Maggs (Duke
 University/Akamai Technologies) and Walter Willinger (NIKSUN\, Inc.)
