A few months ago, on Mastodon one Eduardo Collado approached me and he was asking about the FrysIX pins that I had made. If I could maybe send a couple to him, he'd gladgly distribute them at an upcoming ESNOG event. Upcoming event you say? How's about I come and bring them!? So I mailed the program committee and suggested to bring a presentation on VPP's ability to run Babel and OSPFv3 without the need for IPv4 or IPv6 transit networks. They accepted, and here I am :)
Yesterday, I lined up two opportunities to share my ongoing work on sFlow in VPP: one at FOSDEM'25, for which Luca Deri invited me to submit a call for papers; and another one about network telemetry and observability which Luca is organizing in Zurich. And so, it is proven once again, that NOGs are self-perpetuating. There's always somebody intersted in hearning nerdy stories and I'm always interested in telling them!
This morning, a bunch of the participants went to visit the [Marenostrum] supercomputer at the BSC (Barcelona Supercomputer Center). It is the most powerful supercomputer in Spain, one of thirteen supercomputers in the Spanish Supercomputing Network and one of the seven supercomputers of the European infrastructure PRACE (Partnership for Advanced Computing in Europe). It has ~166K CPU, 390TB of memory and 14PB of storage and is rated to 1.3MWatt of power. The coolest thing ever: it's built into a former chapel named Torre Girona, at the Polytechnic University of Catalonia, where our event is being hosted.
At 10:30 the program kicks off with Ismael Castell's thoughtful presentation about Discovering databrokers - Bringing to light hidden companies. This presentation resonated with me, as there's so much data gathering and inappropriate use of my (and our) personal data on the Internet. This is also why I've taken to selfhosting (Mastodon, Peertube, NextCloud, Immich, Plausible, Roundcube, and several more).
After a coffee break, Gerhard Stein of Flexoptix brings us some theory and practice about Coherent optical transceivers – current capabilities and future capabilities. Then, Jovana Palibrik of Kentik talks about the adoption of RPKI ROV - in particular a huge step-function jump after last year Orange misplaced its password and found its prefixes rerouted and hijacked. Manuel Mendez shared an industry update from Arista with a gazillion different flavors of 400GE optics.
Then we had lunch - very similar to the one yesterday, and I had a chat with the Flexoptix folks. We talked about Return to Office, my sabbatical (and Andrea's too!); and the state of optical engineering. I personally would never have thought in the 90s when I studied this stuff, that it would become such a huge industry!
After lunch, I was invited on stage to bring my presentation entitled VPP: A 100Gbps/100Mpps+ BGP/OSPF router with a single IPv4 address. It was fun to present here - in English and at a reasonably slow pace - and answer a few questions at the end. It was [recorded] and the slides are [online] as well. I also lay out a set of IPng ntag-pins which find new homes with the participants of ESNOG'32 at the University of Technology.
After my talk, Maria Isabel Gandia of CATNIX and Amadeo Beck-Pecoz of ESPANIX give some tips and tricks on how to peer correctly in a talk entitled Como sacar el máximo provecho de los puertos de peering en nodos neutros (English: How to make the most of peering ports in neutral nodes), after which there's one more social-cultural activity: a kahoot!
The kahoot is a quiz with fifteen questions about technology and cultural references from the spanish internet industry and its pioneers. I participate in the kahoot and, despite my Spanish sucking (and delays due to having to translate ES->EN and then my answer back EN->ES), I manage to make the podium together with a player called Edu (Eduardo Taboada who was gracious to give me his book on Proxmox!) and a player called IPv6. I am over the moon that I managed to win here! I take the time to thank the ESNOG organizers, as they did a fantastic job with the logistics and the varied program. I really enjoyed myself!
Then just like that, ESNOG'32 is over. It's 17:00 or so and I make my way back to the hotel, where Marina is already lounging and ready for an apéro. First, we take a little walk through the park and I call my Dad, who is celebrating his birthday today. My parents are doing good, they just got their flu and corona shots (good for them!) and they ask me about my COVID episode last week. We have a good conversation and say our goodbyes - they will be visiting us in Switzerland in December.
At 20:00 we make our way to the city for dinner. It's a bit of a puzzle to find a place that has good tapas, is not too far away, and is affordable. We find a place, honesty not that great though, and we have our food and a bottle of Arienzo wine from the house of Marques de Riscal. On the way back we see a local sight: Zurich, the insurance company, as well has an office in the Diagonal area of Barcelona.
Back at the hotel it's 22:00 and we're both a bit tired. Marina has done a tonne of walking and museum-visiting today, and I spent the day up and about at ESNOG. Interestingly, my Apple watch informs me that I have closed all three rings (12h of standing, 30min of exercize, 950kCal of activity). I would not have thought that!
