The trend toward more peering between networks is commonly conflated with the trend of Internet flattening, i.e., reduction in the number of intermediary organizations on Internet paths. Indeed, direct peering interconnections bypass layer-3 transit providers and make the Internet flatter. This work studies an emerging phenomenon that separates the two trends: we present the first systematic study of remote peering, an interconnection where remote networks peer via a layer-2 provider. Our measurements reveal significant presence of remote peering at IXPs (Internet eXchange Points) worldwide. Based on ground truth traffic, we also show that remote peering has a substantial potential to offload transit traffic. Because remote-peering services are provided on layer 2, our results challenge the traditional reliance on layer-3 topologies in modeling the Internet economic structure. We also discuss broader implications of remote peering for reliability, security, accountability, and other aspects of Internet research.

Sergey Gorinsky received an Engineer degree from Moscow Institute of Electronic Technology, Zelenograd, Russia in 1994 and M.S. and Ph.D. degrees from the University of Texas at Austin, USA in 1999 and 2003 respectively. From 2003 to 2009, he served on the tenure-track faculty at Washington University in St. Louis, USA. Dr. Gorinsky currently works as a tenured Research Associate Professor at IMDEA Networks Institute, Madrid, Spain. The areas of his primary research interests are computer networking, distributed systems, and network economics. His research contributions include multicast congestion control resilient to receiver misbehavior, analysis of binary adjustment algorithms, efficient fair transfer of bulk data, network service differentiation based on performance incentives, and economic perspectives on Internet interconnections and routing. His work appeared at top conferences and journals such as ACM SIGCOMM, IEEE INFOCOM, ACM CoNEXT, IEEE/ACM Transactions on Networking, and IEEE Journal on Selected Areas in Communications. Sergey Gorinsky delivered keynote addresses at NPSec 2013 and RAIT 2012. He has served on the TPCs (technical program committees) of SIGCOMM (2012), INFOCOM (2006-2015), ICNP (2008, 2010-2014), and other networking conferences. Prof. Gorinsky co-chaired the TPCs of COMSNETS 2013, NetSciCom 2014, E6 2012, HSN 2008, FIAP 2008, served as a TPC vice-chair for ICCCN 2009 and TPC area chair for ICNP 2013. He is a member of the COMSNETS Association, a steering committee for COMSNETS conferences.


szeretnélek meghívni Sergey Gorinsky előadására Január 5-én hétfőn 11-kor a BME I épület 210-es termébe. A szeminárium hosszát kb. 1, de az esetleges elhúzódó diszkusszióval sem több mint másfél órára méreteznénk. Sergey főként az idei ACM Conext cikkéről fog mesélni ( ). A Conext konferencia a hálózati architektúrák egyik legkiválóbb fóruma (<18%-os elfogadási rátával). Sergey Európa egyik top kutatója az internet architektúrának.
