DESCRIPTION:By Laurent Vanbever\, ETH ZürichBiography\nLaurent Vanbever i
 s an Assistant Professor at ETH Zürich where leads the Networked Systems 
 Group (NSG) since January 2015. Before that\, Laurent was a Postdoctoral R
 esearch Associate at Princeton University where he collaborated with Profe
 ssor Jennifer Rexford. He obtained his PhD degree in Computer Science from
  the University of Louvain (Belgium) in October 2012. His research interes
 ts lie at the crossroads between theory and practice\, with a focus on mak
 ing large network infrastructures more manageable\, scalable and secure. L
 aurent has won several awards for his research including: the USENIX NSDI 
 2016 community award\; the ACM SIGCOMM 2015 best paper award\; the ACM SIG
 COMM Doctoral Dissertation Award (runner-up)\; the University of Louvain B
 est PhD Award\; the ICNP 2013 best paper award\; and three IETF/IRTF Appli
 ed Networking Research Prizes for his works on inter-domain routing and So
 ftware-Defined Networking (SDN).\nAbstract\nBy centralizing and provisioni
 ng network decisions using a standardized API\, Software-Defined Networkin
 g (SDN) holds great promises for improving the performance and manageabili
 ty of network architectures. Getting there however requires a major softwa
 re\, hardware and even people overhaul. Wouldn’t it be nice to be able t
 o apply the SDN principles on top of existing network architectures\, i.e.
  on good old IP routers\, without having to change  anything? It turned o
 ut that the answer is yes.\nIn this talk\, I will describe two works we ar
 e pursuing in this area along with some prospective ones.\nI will start by
  speaking about Fibbing\, a hybrid SDN architecture that enables any IP ro
 uter to be programmed---not configured---from a logically-centralized cont
 roller.\nTo achieve this\, Fibbing uses distributed routing protocols as A
 PI. More specifically\, a Fibbing controller tricks the routers into seein
 g an augmented network topology composed of fake nodes and fake links that
  is carefully  crafted so that they compute the desired forwarding paths.
  The controller then injects these "lies" into the routing protocols\, and
  the routers simply compute the paths accordingly. Fibbing is surprisingly
  expressive\, scales to large networks\, and quickly reacts to failures. W
 e successfully tested our prototype on unmodified Cisco and Juniper router
 s.\nAlong with Fibbing\, I will also talk about the SDX project in which w
 e are currently improving Internet routing by deploying programmable devic
 es in key locations on the Internet: the Internet Exchange Points (IXP). I
  will present\nthe many opportunities opened by the projects and how we ma
 naged to scale the platform to handle the load of the largest IXPs in the 
 world.
