Abstract : Changing 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 achieving the packet-processing speeds needed in the Internet core, but makes changing the functionality of the network hard, if not impossible.
I will talk about turning the Internet into an "evolvable" network -- one that allows us to try out new network services and experiment with new protocols, 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 mechanisms in response to new problems. I will present RouteBricks, an evolvable router architecture, which consists entirely of off-the-shelf PCs (and can be programmed like one), yet supports line rates of tens of Gbps. I will also show how to use such a router architecture to deploy systematic Internet troubleshooting: I will present Retroactive Sampling, a new packet sampling technique that enables Internet users or regulators to track down packet loss and delay and accurately evaluate the performance of untrusted Internet service providers. Today, deploying such a system would require installing new hardware throughout the Internet; with evolvable network infrastructure, like RouteBricks, it would only require a software upgrade.
Bio : Katerina Argyraki got her PhD in Electrical Engineering from Stanford University in 2007 and is currently a research scientist at EPFL, Switzerland. For her PhD, she developed AITF -- a network-based solution to bandwidth flooding. Before joining EPFL, she worked for Arista Networks, helping build the control plane for high-end 10GbE switches. During her graduate student years, she also worked for Kealia (a developer of video server systems, now part of Sun/Oracle) and BlueArc (a developer of high-end network storage). Her research interests lie in the areas of network architecture and protocols with a focus on programmable routers, network troubleshooting, and denial-of-service defenses.
