The Networked Systems Group (NSG) is a research group in the Department of Information Technology and Electrical Engineering (D-ITET) at ETH Zürich led by Prof. Laurent Vanbever.

Our research interests are centered around complex network management problems, with the larger goal of making current and future networks easier to design, understand and operate. We are currently active in multiple areas including network programmability, data-driven networking, verification, routing, and security. Most of our projects are inherently multidisciplinary and tend to involve recent advances in programming languages, algorithmics, and machine learning.

A few recent examples of practical systems we have built include: Fibbing, iTAP, SDX, SyNET, SDNRacer, and SWIFT. We are also currently looking at the impact of routing on systems overlays such as cryptocurrencies.


Maria Apostolaki receives one of the IRTF/IETF Applied Networking Research Prize 2018!

Maria got nominated for her work on routing attacks on cryptocurrencies which got published at the IEEE Symposium on Security and Privacy. This is the fourth ANRP prizes our group receives, after DRAGON, Fibbing, and our work on seamless BGP reconfiguration.


Three papers accepted at NSDI 2018!

Our group starts 2018 in the best way possible with three accepted papers at the upcoming NSDI! Stay tuned to learn about: automated network captioning and network reasoning (with Net2Text), declarative traffic mirroring (with Stroboscope), and partial network configuration synthesis (with NetComplete).
