DESCRIPTION:Dr. Katerina Argyraki - IC Faculty candidate\nAbstract : Chang
 ing the Internet architecture is notoriously difficult.  A key reason for 
 this difficulty is that today's Internet infrastructure is mainly built on
  specialized hardware.  This has long been considered a prerequisite for a
 chieving the packet-processing speeds needed in the Internet core\, but ma
 kes changing the functionality of the network hard\, if not impossible.\n\
 nI will talk about turning the Internet into an "evolvable" network -- one
  that allows us to try out new network services and experiment with new pr
 otocols\, without having to install new specialized equipment every time. 
  This would enable us\, for instance\, to continually evolve the Internet'
 s defense mechanisms in response to new threats\, or its troubleshooting m
 echanisms in response to new problems.  I will present RouteBricks\, an ev
 olvable router architecture\, which consists entirely of off-the-shelf PCs
  (and can be programmed like one)\, yet supports line rates of tens of Gbp
 s.  I will also show how to use such a router architecture to deploy syste
 matic Internet troubleshooting: I will present Retroactive Sampling\, a ne
 w packet sampling technique that enables Internet users or regulators to t
 rack down packet loss and delay and accurately evaluate the performance of
  untrusted Internet service providers.  Today\, deploying such a system wo
 uld require installing new hardware throughout the Internet\; with evolvab
 le network infrastructure\, like RouteBricks\, it would only require a sof
 tware upgrade.\nBio : Katerina Argyraki got her PhD in Electrical Engineer
 ing from Stanford University in 2007 and is currently a research scientist
  at EPFL\, Switzerland. For her PhD\, she developed AITF -- a network-base
 d solution to bandwidth flooding. Before joining EPFL\, she  worked for Ar
 ista Networks\, helping build the control plane for high-end 10GbE switche
 s. During her graduate student years\, she also worked for Kealia (a devel
 oper of video server systems\, now part of Sun/Oracle) and BlueArc (a deve
 loper of high-end network storage). Her research interests lie in the area
 s of network architecture and protocols with a focus on programmable route
 rs\, network troubleshooting\, and denial-of-service defenses.
