Our paper on the Mini-Internet platform selected for the ACM SIGCOMM 2020 Best of CCR session!

"An Open Platform to Teach How the Internet Practically Works" is one of the three papers selected for being presented at ACM SIGCOMM 2020 in the Best of CCR session. Congratulations to the whole development team, and especially to Thomas, Tobias, and Tino!

P4 Learning is getting traction

Our public repository containing pedagogical material, demo and exercises to learn P4 programming has reached the symbolic bar of 100 stars on GitHub! Congratulations to Edgar who put most of the material together!


"Probabilistic Verification of Network Configurations" accepted at ACM SIGCOMM 2020!

Stay tuned to learn how one can verify not only "hard" network properties that must hold all the time, but also probabilistic properties that must hold a fraction of the time (such as Service Level Agreements).


New NSG member: Romain Jacob joins us as post-doc!

Romain obtained his PhD from ETH Zurich (ITET) under the supervision of Prof. Lothar Thiele. Welcome!


3 NSG lectures this Fall

Our group will offer three lectures this semester including a completely renewed Advanced Topics in Communication Networks lecture which will focus on advanced topics in Internet routing and forwarding. We'll also offer a seminar on Communication Networks (in collaboration with D-INFK). Finally, and as usual now, we'll teach the first part of Discrete Event Systems together with Prof. Lothar Thiele and Prof. Roger Wattenhofer. Check out our course webpage for more info.


Promotion to Associate Professor!

Laurent got promoted to Associate Professor (with tenure) by the ETH Board!


Coralie Busse-Grawitz receives the ABB Research Award!

Coralie Busse-Grawitz, one of our master students and future PhD student, is one of this year's recipients of the ABB Research Award (ABB Forschungspreis) for her Master's Thesis entitled "In-Network Inference with Random Forests". She received the award at this year's "ETH Tag" on 16 November.


Goldene Eule 2019!

For the second time after 2016, Laurent has been awarded the Golden Owl of the VSETH! The Owl is awarded by the VSETH, ETH Zurich's students association, and "honours lecturers who have provided exceptional teaching". Huge kudos to the teaching assistants from NSG without whom this wouldn't have been possible!


“(Self) Driving Under the Influence” accepted at ACM HotNets 2019!

Stay tuned to learn about how adversarial traffic inputs can mislead “data-driven” networks.


Final version for our upcoming two NSDI 2020 papers available

We just uploaded the final versions of our two upcoming NSDI 2020 papers: Config2Spec (specification mining) and SP-PIFO (programmable scheduling). Check them out! 


The first NSG PhD graduate!

Ahmed El-Hassany is the first PhD student graduating from our group! You can check out his work on network configuration synthesis and network verification here.


ERC Starting Grant 2019!

Laurent got awarded an ERC Starting Grant. The grant (SyNET) aims at automatically generating correct network configurations rather than verifying them. This also means that our group will soon recruit PhD students and postdocs. Ping us if interested!


New seminar lecture on "Learning, Reasoning and Control" in the context of Communication Networks

Starting from this fall, our group will offer a new seminar lecture. This year's topic will be "Learning, Reasoning and Control" in the context of communication networks. You can find more information about the seminar on our website: Please note that the number of seats is limited to 24.


Two papers at NSDI 2020!

We got two accepted papers at the upcoming NSDI (Spring deadline)! Stay tuned to learn about how to automatically "mine" network specifications from existing configurations (with Config2Spec) and how to closely approximate the behavior of programmable packet schedulers at scale, and on existing devices (with SP-PIFO).


If you're interested in programmable data planes, check out our (open) course materials

This semester we taught our first lecture on programmable data planes (check out the rest of our courses). Today we're happy to release all our materials including: slides, docs, examples, VM, and 7 weeks of detailed P4 exercises (with solutions): GitHub: Course Website:


"Blink: Fast Connectivity Recovery Entirely in the Data Plane" accepted at Usenix NSDI 2019!


"SABRE: Protecting Bitcoin against Routing Attacks" accepted at NDSS 2019!


"Hardware-Accelerated Network Control Planes" accepted at HotNets 2018!


Our new lecture "Advanced Topics in Communication Networks" starts in September

See for more details.


"NetHide: Secure and Practical Network Topology Obfuscation" accepted at Usenix Security 2018!


Check out our new website on Automated Network Captioning (i.e. network chatbots)

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.


Bayonet: Probabilistic Inference for Networks conditionally accepted at PLDI 2018!


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).


New website!

Welcome to our brand new website! Stay tuned for more content.
