DESCRIPTION:Routing and scheduling are two of the most fundamental tasks p
 erformed by any network. Routing determines the set of paths alongside whi
 ch network traffic flows\, while scheduling controls how traffic flows alo
 ngside these paths.\n\nToday\, these two tasks strike different trade-offs
  in terms of flexibility and speed. As it runs in the control plane\, in s
 oftware\, routing tends to be flexible... but slow. In contrast\, as it ru
 ns in the data plane\, most of the time in hardware\, scheduling tends to 
 be inflexible... but fast.\n\nIn this talk\, I will argue that this trade-
 off is not fundamental thanks to the recent advent of programmable data pl
 anes. More specifically\, I will first argue about offloading (some) routi
 ng tasks to the hardware\, so as to make them much faster. I will then arg
 ue about making packet scheduling programmable\, so as to make it much mor
 e flexible. I will illustrate each proposal with examples of our recent wo
 rks including Hardware-Accelerated Control Planes [HotNets'18]\, Blink [NS
 DI'19]\, and SP-PIFO [NSDI'20].\n\nBio:\n\nLaurent Vanbever is an associat
 e professor at ETH Zürich where he started as an assistant professor in 2
 015. Before that\, Laurent was a postdoctoral research associate at Prince
 ton University where he worked with Jennifer Rexford. He obtained his PhD 
 degree in Computer Science from the University of Louvain in 2012. His res
 earch focuses on making large network infrastructures more manageable\, sc
 alable and\, secure. Laurent has won several awards for his research inclu
 ding: the NSDI community award\; the SIGCOMM best paper award and six IETF
 /IRTF Applied Networking Research Prizes.
