Couldn’t make it to NSDI ’25 or missed my talk? Here’s the recording: youtube.com/watch?v=6g8Zfx3Y… We presented PACKS, the first programmable scheduler to approximate PIFO across all dimensions — showing why both admission control and scheduling matter in programmable scheduling.

This was joint work with Balázs Vass, @PooriaNamyar, Behnaz Arzani, @littleredspam, and @lvanbever, conducted prior to my joining NVIDIA. Full paper: usenix.org/system/files/nsdi…

Honored to receive the 2024 ETH Medal for Outstanding Doctoral Dissertation. My heartfelt thanks to Laurent Vanbever, Nick McKeown, and Mohammad Alizadeh, as well as the ETH Zürich faculty, for the recognition. I couldn’t have asked for a better way to conclude my PhD journey. 🙏

Tomorrow, @akshayknarayan will discuss how the Internet should manage bandwidth allocation at SIGCOMM'24. He will present Recursive Congestion Shares (RCS), a framework to provide CCA-independent bandwidth allocations that are consistent with the Internet’s economics. 🙌🚀

Our paper, "Everything Matters in Programmable Scheduling," has been accepted at NSDI'25! 🎉🎉 We propose PACKS, a programmable scheduler that approximates both PIFO's scheduling and admission behaviors. Joint work with our friends at BME-TMIT, USC, and Microsoft. Pre-print 👇

Had a blast presenting QVISOR at #HotNets23 🚀 First time at HotNets and MIT, and it was phenomenal. Top-notch format, and incredible audience—such a fantastic experience! 🙌🙌 Thanks much to the organizers! You can check out the slides of my talk here: nsg.ee.ethz.ch/files/public/…

Very happy to share that I'll be visiting the Berkeley NetSys Lab at @UCBerkeley for the next few months. It will be an honor to work under the guidance of Prof. Sylvia Ratnasamy and Prof. Scott Shenker. If you happen to be in the area, let's chat! 🚀🚀

Check out this paper from the P4 Euro Workshop by individuals from the Swiss Federal Institute of Technology, Zurich. They discuss an approach that reduces the voluminosity of P4 code and share findings | bit.ly/3WJmXJ5 @ETH_en #P4 #P4Euro

Sorting my room I found this newspaper from 2015 in which they interview @martin_casado. Back then, I had not even finished my Bachelor's and most probably did not know about SDN... Still, for some reason I decided to store it. Today, needless to say..🙈 Our destiny is written😜

I had a lot of fun yesterday presenting O4 at #EuroP4. By introducing three simple constructs to P4 -- arrays, loops, and factories -- O4 reduces code volumes significantly while preserving P4's expressivity and fine-grained control 🚀🙌. Slides here: albertgran.com/assets/pdfs/o…

1) Over the past decade, programmable networks have gone from dream to reality 🚀. But why do network owners want to program the network?🤔

3) "This means providing reliable service even under uncertain operating conditions, which requires (i) selecting particular forwarding paths, and (ii) prioritizing certain packets over others—i.e., controlling packet scheduling at line rate.⚡️"

4) This intro made my day 🙌. Five years ago, @lvanbever invited me to join his group as Master's student to work on predictable networks in p4, which I didn't know🙃. Today, four years into my PhD, I couldn't be happier of that decision: it seems we took the right direction.🚀
