+
+We have descended upon Upper Diagonal in the North of Barcelona. It's a beautiful neighborhood, I
+can tell it's _upscale_ with large avenues lined with trees, big houses with well kept yards, and
+it's super clean. Did we land in the posh neighborhood? Our hotel is top notch, and I slept  really
+well last night. Marina will be visiting the Picasso, Miro and maybe a few others today. I will be
+joining the Spanish Network Operators Group _ESNOG_ for their 32nd rendition of a one and a half day
+meeting to exchange ideas, projects, proposals and industry updates with one another.
+
+I chose the hotel to be walking distance from the venue, which is the Barcelona university of
+technology, called the _Universitaria Politecnica de Catalunya_ or _UPC_ for short. The organizers
+have chosen a very handsome building which houses an auditorium for about two hundred people or so.
+There's a good eighty people at the venue today.
+
+I don't take breakfast at the hotel, and instead walk over to the UPC building through the park.
+It's a nice stroll and the weather is gorgeous out: light blue skies with a bright yellow Sun that
+is happy to see me. Once at the university, I am quickly checked in and take my seat. I've promised
+Carlos that I would avoid the social activity later today, just out of an abundance of caution even
+though I have tested negative for COVID'19 on the way out to Barcelona. Besides, Marina is with me
+and having a nice quiet dinner is also fun.
+
+The program is varied and quite interesting. We start off with Paolo Lucente of NTT who wants to
+share some modernization in a talk entitled Network Telemetry - Exploring Technologies and
+Advancements in Standardization. Eduardo Taboada is next - he literally _wrote the book_ on Proxmox:
+The Open Code Virtualization Solution for the Future. His narrative goes into the purpose, features,
+use cases and vision of virtualization.
+
+During the break for coffee, I meet a few of the other participants and we talk about our network,
+what we do, what we're working on. The coffee is outside in the back yard of the university, and
+there's some scones and little tartelettes: breakfast! After the break, Victor Serrano of Nokia
+disserts on "Lab as Code" with Nokia Containerlab. I realize that it may be a good idea to
+contribute VPP images to _Containerlab_, so that folks can add these machines and learn from them.
+
+Jose Antonio Montes is a telephony person - his talk is called "Put some FOSS on your VoIP". I'm
+reminded of the [[FrysIX Barbecue]({{< ref wk7day6.md >}})where I met Joran Osinga, who has built
+and shown/documented a fully working 5G radio network - we talked about it on (an upcoming episode
+of the) Fusix Podcast. Michela Galante continues with a talk showing how to update the Ripe Database
+information in an automated way using the API.
+
+As I take a quick bathroom break, I bump into Nick of Nexgen and he offers me a coffee. We sit and
+chat outside for a ltitle bit, talking about coherent optics, CWDM vs DWDM/OWDM and what new types
+of transmission in the 400GE arena are up and coming. It's super interesting to hear from Nexgen,
+and I'm sure IP-Max will be pleased as well as a new and very happy customer.
+
+Lunch is served in the yard - it's sliders, little finger food, fizzy drinks, mate, coffee/tea
+and water. I enjoy catching up with Luca Deri (the ntop tech-lead), and we talk about my current
+project in VPP to add sFlow. He's pretty excited about it, and makes me a promise: he intends to
+move the sFlow receiver to the open source [[ntopng](https://www.ntop.org/products/traffic-analysis/ntop/)]
+and I think that would be a wonderful feature! We also talk about an upcoming conference he is
+organizing in Zurich, for which he extends me an invitation to speak. Of course, Luca is still
+active at [[FOSDEM](https://fosdem.org/)] and will be kicking off the CfP for the network devroom
+soon. I may be interested to join - even though I find that FOSDEM is way too crowded and busy,
+they have significantly outgrown the capacity of the university in Brussels, but they're not
+interested in re-evaluating the attendee body "the more the merrier", but it's pretty clear to me
+that the organizers have lost touch with the situation on the ground: almost invariably if you're
+not _in_ a devroom at 08:30, you will be out of luck: moving between them is impossible, doors are
+closed because they are (over)full, and you end up watching the same talk online in the hallway.
+Really terrible user experience! But, joining the Network devroom and staying there the whole day, I
+can do that :)
+
+After lunch (which ends at 15:15, I still find that funny), Octavio Alfageme discusses a multicast
+protocol in a talk titled "What do we see tonight? BIER and the evolution of multicast distribution
+architectures.". I know that VPP has a BIER implementation - I should really look in to this a bit
+more, as multicast always was just a little bit out of reach for me. Maybe IPng Networks is a nice
+place to roll out some multicast or other.
+
+A set of peering updates is next. Maria Isabel Gandia of CATNIX is joined by Javier Achirica of
+ESPANIX. Although I've seen Isabel around, the DE-CIX slot remains empty. After these updates, we
+are joined by Christian Adell [who once gave me a book!], Design-Driven Source of Truth, the
+Complete Lifecycle which is a practical constraints-based automation to build and destroy network
+sites and point-to-point networks.
+
+Luca Deri closes out the day with a presentation (in English, _grazie mille_!) which showcases a
+range of tools and traffic inspection techniques that we have developed over the years. These
+innovations have been at the construction of a robust platform capable of delivering detailed
+network visibility at high-speed using standard, commodity hardware.
+
+At 18:15 or so I decide to take off - there's a beering session a little ways away from the
+university, and a dinner at 21:00; but I have dinner plans with Marina. We decide on a place called
+[[Casa Petra](https://www.casapetrarestaurante.com/menus)] which is not fancy, but very well done
+tapas. Our absolute favorite is a tomato tartar, which has a thick and rich flavor. I also enjoyed
+all the other dishes - boquerones (English: Anchovies) and Pan con Tomate (English: bread with
+tomato), the Jam&oacute;n Iberico (English: Iberian cured ham), and a fried artechoke with snippets
+of dried ham. And of course, the drop of wine from LaFou that went with the tapas.
+
+At 22:30 we get back to the hotel and Marina wants to finish watching her movie on the iPad. So, I
+decide to finish something I started a few days ago, and motivated by my conversation with Luca:
+completing the API for the `sFlow` plugin. Until now, we had only a few _setters_. I refator the
+code to rename them to `*_set()` calls, and accompany each with a pairing `*_get()` call. I also add
+a dumper command, to enumerate either one or all sFlow enabled interfaces. With that, I should be
+able to integrate the entire plugin cleanly in [[vppcfg](https://github.com/pimvanpelt/vppcfg.git)].
+I wrestle a little bit with the unit tests, and end up committing patchset
+[[#13](https://gerrit.fd.io/r/c/vpp/+/41680/12..13)] which still passes all integration tests.
+Whoot, Vino-Coding rocks :)
+
+Tomorrow morning there will be a tour of Mare Nostrum, a local barcelona supercomputer. Then at
+10:00, the second day of ESNOG'32 will start. I go to sleep a happy camper.

+
+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](https://en.wikipedia.org/wiki/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](https://video.ipng.ch/w/i4ibtvEkUmEE39mkCNeDzQ)] and the slides are
+[[online](https://go.ipng.ch/esnog32)] 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 ap&eacute;ro. 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!
