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.
