About the Talk

Over the past few years, Software-Defined Networking (SDN) has gained significant traction in both the industry and the research community. Reasons for this success include the promises of making networks more flexible, and easier to manage and to operate. However, incrementally or partially deploying SDN is a challenge for network operators as they need to figure out how to make two radically different routing paradigms, centralized and distributed, to cooperate.

In this talk, we explore solutions for integrating SDN within existing routing systems in such a way that SDN capabilities can be realized without requiring a full deployment. We consider both intra-domain (IGP) and inter-domain (BGP) routing protocols. For IGP, we show how a SDN controller can leverage existing protocols as a provisioning interface to control, in a centralized way, the forwarding paths computed by the routers, in a distributed way. For BGP, we show how SDN-enabled peering points can provide advanced data-plane security (e.g., preventing policy violation), fine-grained traffic engineering (e.g., wide-area load balancing), sub-second convergence, and better monitoring capabilities than what is currently achievable.

About the Speaker

Laurent Vanbever is a Postdoctoral Research Associate at Princeton University working with Prof. Jennifer Rexford. He completed his PhD at the University of Louvain, Belgium in October 2012 under the supervision of Prof. Olivier Bonaventure. Prior to that, he obtained his master degree in computer science engineering from the University of Louvain in 2008 and a master degree in management from the Solvay Brussels School of Economics and Management in 2010. His research interests focus on Software-Defined Networks, IP routing, and network management.
