Couldn’t make it to NSDI ’25 or missed my talk?
Here’s the recording: https://t.co/Ow4FRi6uNI
We presented PACKS, the first programmable scheduler to approximate PIFO across all dimensions — showing why both admission control and scheduling matter in programmable scheduling.

Happy to be featured in the Nova 111 List 2025 as one of Spain's top professionals under 35. Yet another meaningful acknowledgement of the research I conducted during my PhD. Grateful to the jury and the organization for this recognition 🚀

[Albert Gran Alcoz @albertgran]

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. 🙏

I am delighted to share that I have started a new role at @nvidia as a Senior Performance Research Engineer. I am very grateful for the opportunity and looking forward to contributing my best to the company. #NVIDIAlife 🚀

Very happy to receive the CYD Award 2024 for Outstanding Publication for "Aggregate-based Congestion Control for Pulse-Wave DDoS Defense" (ACM SIGCOMM 2022) 🏆🚀

Kudos to @MasorX, @VLenders, @lvanbever, and thanks to the Cyber-Defence Campus and armasuisse for the recognition 🎉

[Albert Gran Alcoz @albertgran]

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.

I am very happy to share that I have successfully defended my PhD! 🎉

To everyone who contributed in one way or another to making this possible, thank you.

It has been an incredible ride, and I have enjoyed every bit of it.

Now, time to think about the next chapter. 🚀

[Albert Gran Alcoz @albertgran]

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: https://t.co/2c9yRmQsWc

[Albert Gran Alcoz @albertgran]

Very excited to start as a PhD Research Intern at @Cloudflare. Grateful for this opportunity and looking forward to helping build a #BetterInternet 🚀

[Albert Gran Alcoz @albertgran]

Our paper “QVISOR: Virtualizing Packet Scheduling Policies” has been accepted at HotNets'23  🎉🎉  Can we simultaneously deploy multiple scheduling algorithms on existing commodity switches? Pre-print: https://t.co/xrRGv7YECK 🚀🚀🇺🇸 #hotnets23

[Albert Gran Alcoz @albertgran]

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! 🚀🚀

[Albert Gran Alcoz @albertgran]

@PurdueECE Heartiest congrats, @vishiit 🙌🚀

[P4 @P4lang]

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 | https://t.co/bc7u0NBxrL

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😜

[Albert Gran Alcoz @albertgran]

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: https://t.co/SWzrU9PR6n

@natefoster @P4lang @ACMSIGCOMM @intelfabric Hi Nate, thanks much for your work 🚀 Are the results of this study publicly available anywhere? I am looking for some numbers to motivate the growth and dominance of p4 language in data-plane programming. I already have some basic stats, but yours sound much more interesting 🙂
