|

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 Jamón 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.
