The Internet is a diverse ecosystem where a multitude of networks interconnect to provide end users with a global reach. Interconnection agreements supply economic incentives for networks to deliver traffic along end-to-end paths. Driven by the rapid Internet adoption, unrelenting traffic growth, and increasing demands for performance and quality, Internet interconnections evolve and affect traffic routing.

In this seminar, we first explore an emerging phenomenon of remote peering, an interconnection where remote networks peer via a layer-2 provider. While our measurements reveal significant presence of remote peering at IXPs (Internet eXchange Points) worldwide and a substantial potential to offload transit traffic, we also discuss implications of remote peering for Internet topology modeling. Then, we propose Route Bazaar, a new architecture for flexible Internet connectivity. Inspired by cryptocurrencies, the use of a block chain in Route Bazaar enables multilateral contracts for end-to-end routing with QoS (Quality of Service), rich private policies, and public accountability.

The seminar is based on joint work with my student Ignacio Castro and our collaborators Camilo Cardona, Pierre Francois, Aurojit Panda, Barath Raghavan, and Scott Shenker.

Bio: 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 , ACM CoNEXT, IEEE INFOCOM , 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), CoNEXT (2015), INFOCOM (2006-2016), ICNP (2008, 2010-2015), 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.
