Our paper entitled "Learning to Configure Computer Networks with Neural Algorithmic Reasoning" was accepted at NeurIPS 2022! In this paper, we explain how we can approximate routing computations using neural networks. Among others, doing so allows us to efficiently "invert" these computations enabling to automatically synthesize configurations from their intended output. This synthesis problem is known to be hard: actually, our recent ICNP 2022 paper shows that many instances of that problem are NP-hard/NP-complete. Having a away to approximate these computations allows us to "break" the inherent scalability barrier of solving these problems, at the price of accuracy. How to deal with this accuracy loss is amongst the many next questions we want to look at. Stay tuned!
Our group will have two papers at this upcoming ACM HotNets workshop! These two papers will mark our 10th and 11th HotNets papers since 2014.
Stay tuned to learn more about:
1) How we plan to build the next-generation of network traffic generator by leveraging millions of code repositories hosted on code-sharing platforms such as GitHub;
2) How we intend to build generalizable machine learning (ML) models for predicting network traffic dynamics using the Transformer architecture.
As usual, you'll find the final version of the papers on our publications page in a couple of weeks.
This summer treated us well thus far, with no less than five papers acceptance! Stay tuned to learn more about:
As usual, all the papers will be made available on our publications page.
2021, wrapped! Check out our activity report to see what our group has been up to in terms of research and teaching activities. Spoiler alert: 2021 was busy, but fulfilling!
Curious about what happened in the Internet in 2021? Check out this print depicting 1 year worth of BGP routing announcements observed on 256 Internet routers. "Behind the scenes" information available here.
Laurent gave the introductory keynote at ACM CoNEXT 2021. The talk is entitled "The three tales of (correct) network operations" and summarizes our 10-year (and counting!) journey exploring the operational aspects of routing algorithms, focusing on three aspects in particular: verification, synthesis, and reconfiguration. You can find the slides here.
Tibor Schneider is one of this year's recipients of the ABB Research Award (ABB Forschungspreis) for his Master's Thesis entitled "Snowcap: Synthesizing Network-Wide Configuration Updates". He received the award at this year's "ETH Tag" on 20 November.
Laurent was selected for the 2021 ACM SIGCOMM "Rising Star" Award. The award is in recognition for outstanding research contributions, early in his career, toward improving the flexibility, correctness, and security of Internet routing. More information about the award and past recipients can be found online.
Maria Apostolaki (2nd PhD student to graduate from NSG) will join Princeton's Electrical and Computer Engineering Department (ECE) as a tenure-track assistant professor in the Fall of 2022! Huge congrats to her!!
Laurent will co-chair ACM HotNets 2021 (the ACM Workshop on Hot Topics in Networks) together with Prof. Minlan Yu from Harvard.
2020 has been a really "particular" year—including for our research group. And yet, despite everything, 2020 was also a good year for us. Check out our latest activity report to learn more about our research and teaching activities (and successes) in 2020.
Laurent gave the keynote talk at EuroP4 (the 3rd P4 Workshop in Europe). He spoke about data-plane offloading (in the context of routing tasks) and programmable packet scheduling. You can check the talk on YouTube here, and the slides here. The talk is based on three recent NSG projects: Hardware-Accelerated Network Control Planes [HotNet's18], Blink [NSDI'19], and SP-PIFO [NSDI'20].
After having won two Golden Owls in 2016 and 2019, Laurent has been awarded the Credit Suisse Award for Best Teaching! The aim of the prize, which is awarded by the student association VSETH, is to promote quality teaching, and to strengthen Switzerland as a science and research location. Huge kudos to our teaching assistants without whom this wouldn't have been possible!
Our paper on probabilistic network verification won one of the two "Best Student Paper Awards" at SIGCOMM 2020! Congrats to the entire team, and especially to Sam, the project lead.
Besides reading the paper, you can learn more about the project by trying out the code or by watching the presentation.
"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!
Read more about the project in this APNIC blog post.
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).
Romain obtained his PhD from ETH Zurich (ITET) under the supervision of Prof. Lothar Thiele. Welcome!
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.
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.
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!
Stay tuned to learn about how adversarial traffic inputs can mislead “data-driven” networks.
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!
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: seminar-net.ethz.ch. Please note that the number of seats is limited to 24.
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).
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: https://github.com/nsg-ethz/p4-learning Course Website: https://adv-net.ethz.ch
See adv-net.ethz.ch for more details.
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.
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).
