SDX: A Software Defined Internet Exchange
Meeting:	NANOG59
Date / Time:	2013-10-07 1:30pm - 2:00pm
Room:	Akimel Ballroom 3 & 4
Presenters:	Speakers: Arpit Gupta Arpit Gupta is currently a first year PhD student at Georgia Tech. At Georgia Tech he works under supervision of Dr. Nick Feamster and is also guided by Dr. Jennifer Rexford, Princeton and Dr. Scott Shenker, UC Berkeley for his SDX project. His research focuses on role of Internet Exchange Points (IXPs) in current Internet and how to improve interdomain routing using SDN. Before joining Georgia Tech, he completed his MS from North Carolina State University and B.Tech from Indian Institute of Technology, Roorkee, India.
Abstract:	Deploying software-defined networking (SDN) at Internet Exchange Points (IXPs) offers new hope for solving longstanding problems in interdomain routing. SDN allows direct expression of more flexible policies, and IXPs are central rendezvous points that are in the midst of a rebirth, making them a natural place to start. We present the design of an SDN exchange point (SDX) that enables much more expressive policies than conventional hop-by-hop, destination-based forwarding. ISPs can apply many diverse actions on packets based on multiple header fields, and distant networks can exercise ``remote control'' over packet handling. This flexibility enables applications such as inbound traffic engineering, redirection of traffic to middleboxes, wide-area server load balancing, and blocking of unwanted traffic. Supporting these applications requires effective ways to combine the policies of multiple ISPs. Our SDX controller provides each ISP the abstraction of its own virtual switch and sequentially composes the policies of different ISPs into a single set of rules in the physical switches. Preliminary experiments on our operational SDX demonstrate the potential for changing interdomain routing from the inside out.
