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. We are also part of the ETH ICE center, a new group initiative on programmable and dependable networked systems.

Our research interests are centered around complex network management problems, with the larger goal of making current and future networks (especially the Internet) 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: BayonetFibbingiTAP, Net2Text, NetComplete, NetHideSDX, SyNET, SDNRacer, Stroboscope, and SWIFT. We are also currently looking at the impact of routing attacks on systems overlays such as cryptocurrencies and anonymity networks. To learn about our work, please check out our research and publications pages.

Our flagship lecture is Communication Networks offered in the Spring semester. We also offer a new lecture on Advanced Topics in Communication Networks in the Fall semester. Check our courses page for more information.

We just released our new website ( covering our work on network explainability with Net2Text. Check it out to see how we can make networks "talk" proper English.
