Coherent optical transceivers - current capabilities and future possibilities (denog15)

With the speed of 400G coherent technology was introduced to pluggable optical transceivers (OIF 400ZR and OpenZR+). This technology is complex and powerful for your network, it even has influence on your network device operating system. This talk will provide first insight in Nokia's implementation as well as known or potential interoperability issues addressed by the OIForum. If your transport system, router or even switch already provides coherent pluggable transceivers check the available interface parameters. You can send me these CLI outputs / management software screenshots to [email protected]. I will try to include it into the presentation. And finally new formfactors for 800G and 1,6T will be part of the game as well. Stay tuned.... None about this event: https://pretalx.com/denog15/talk/KBPMVV/

Feediverse independencies and network diversity (denog15)

With the rise and fall of social networks, decentralized networks, and new spin-offs were moved in the focus of the public. One significant benefit of advertising non-commercial social networks is diversity and the ability to self-host. Independence should give federated networks more resiliency against the power of certain actors. This talk will examine the dispersion of federated instances in the wild. Where are hotspots? What are the networks and ASNs the Fediverse lives in? None about this event: https://pretalx.com/denog15/talk/MM7GST/

Towards automated and proactive anomaly detection in fiber access networks (denog15)

Communication networks are vital for society and network availability is therefore crucial. There is a huge potential in using network telemetry data and machine learning algorithms to proactively detect anomalies and remedy network problems before they affect the customers. In practice, however, there are many steps on the way to get there. In this presentation we would like to share the status of an ongoing research collaboration with the purpose of simplifying the operation and increase the availability of fiber access networks. The research project is part of a CELTIC_NEXT flagship research program (AI-NET) that has the overall target of accelerating the digital transformation in Europe by intelligent network automation. The project (“Palantir”) consists of two parts: A field trial in a Swedish municipality network where telemetry data from more than 500 access switches, connecting more than 12000 households, are collected and analyzed for anomalies using machine learning. (The field trial is planned to be expanded to cover 1000 access switches during the project and synthetic errors are planned to be injected to emulate error situations.) The second part is a demonstrator to be set up at Fraunhoffer HHI in Berlin (starting in October 2023). The demonstrator covers an end to end network and aims to demonstrate all aspects of the research program. In the presentation we would like to describe our field trial and demonstrator, share our experiences in collecting and analyzing telemetry data in the field and describe our conclusions so far. We would also like to open up for a discussion with the DENOG15 participants on what real life error situations that causes the most problems in fiber access networks and whether they would be suitable for AI detection (and potentially also for error emulation in our field trial). Project Palantir is a collaboration between: • Fraunhofer HHI (German Research Institute): Demonstrator • Lunet (Swedish operator - open access municipality network): Field trial • RISE (Independent Swedish research institute): Field trial • Savantic (Swedish AI specialists): Field trial • Waystream (FTTX vendor): Field trial and demonstrator None about this event: https://pretalx.com/denog15/talk/8AN7PV/

Private relay services – Insights from an access-network perspective (denog15)

The market has gathered more than a year’s experience with Private Relay, which Apple introduced with iOS15. We want to shed some light on the traffic profile visible from an access-network perspective. So far, the market has not seen a major uptake in Apple Relay services, it is still in the permille range of total traffic. However, operators have voiced concerns about how such services, if deployed widespread, could impact the ability to manage capacity, traffic and availability effectively. The architecture is well documented by Apple and the three CDNs operating egress-proxies, Akamai, Cloudflare and Fastly. But how does the traffic look in real life? Does content localization work as expected? Such questions are yet to be adequately answered. We used flow-based data from affiliated networks to investigate the parts of the traffic flows which are visible to an access network and applied the documentation of the relay architecture to understand what we see. What we can clearly see is that traffic behaves less structured compared to a comparable non-relay stream. Also, debugging is extremely challenging, as the Private Relay design is purposely effectively hindering an end-to-end view for any involved party.

Moving your mobile customers from IPv4 to IPv6 (denog15)

Between 2015 and 2021, in Germany, Deutsche Telekom has first enabled Dualstack IPv4 and IPv6 for their mobile subscribers, and then successfully transitioned most of them into an IPv6-only access model. This talk will highlight the rationale, the planning phase, the different testing stages as well as the implementation and the migration of the customer base. You will also learn some basics on how IPv6 works in 3GPP mobile networks, and a lot of lessons learnt will be shared. None about this event: https://pretalx.com/denog15/talk/VBY7QP/

Looking good! (godotcon2023)

One of the biggest prejudices amongst the game dev community that has not tried Godot yet is that the engine is “only good for 2D games!”. Every day Godot is improving its capabilities to render 3D environments more and more, and to put these prejudices to the ground, we took three months to try to achieve the best graphical quality we could for our next game. Come join us in this talk where we talk about what a team of two people, an artist and an engineer, learned from this experience, what’s amazing, what could be improved, and what didn’t work: Godot 4.2 capabilities, importing assets from Blender to Godot, rendering techniques, workflow, topology, material blending, asset management, level of detail and much more. about this event: https://pretalx.c3voc.de/godotcon2023/talk/godotcon202331/

Panel: Die De-Militarisierung von Cybersicherheit? (fiffkon23)

Die De-Militarisierung von Cybersicherheit? Perspektiven und Fragen aus der Soziologie und den feministischen science and technology studies Attacken, Verteidigung, Schwachstellen oder der Faktor Mensch - Cybersicherheit ist durchzogen von militärischen Metaphern. Diese werden in alarmistische und moralisierende Kommunikationsstrategien übersetzt. In diesem Panel diskutieren Soziolog:innen und science and technology studies-Forscher:innen, wie Cybersicherheit über militärische Narrationen hinaus konzeptionalisiert werden kann. Wir versammeln empirische Einblicke in diverse Felder: Expertendiskurse (Hacker und Internetgovernance), klein- und mittelständische Unternehmen, Softwareentwicklung, Wissensvermittlung und Kommunikationsinfrastrukturen. Hier werden gänzlich konfligierende Register der Cybersicherheit sichtbar: verteilte Verantwortung, unlösbare Dilemma, kollaborative Arbeit und sogar Fürsorge für Geräte und soziotechnische Gefüge. about this event: https://fahrplan.2023.fiffkon.de/fiffkon23/talk/WRJWP8/

ICT4D trifft auf digitalen Kolonialismus und Überwachungsstaat (fiffkon23)

ICT4D trifft auf digitalen Kolonialismus und Überwachungsstaat oder “The New Scramble for Africa” Unter dem Schlagwort ICT4D („Information and Communication Technology for Development“) treiben die GIZ und andere Entwicklungsagenturen seit einigen Jahren die Digitalisierung der Entwicklungszusammenarbeit voran. Dabei setzt man nicht nur auf Hype-Technologien wie Blockchain, Big Data und künstliche Intelligenz, sondern versucht auch Bildungsinhalte und Organisationsformen wie digitale Startups zu transferieren. Entwicklungsagenturen treffen in den Ländern des Südens auf Regierungen, die (oft mit chinesischer Hilfe) digital aufrüsten, um eine Wiederholung des Arabischen Frühlings zu verhindern, und auf expansionistisch getriebene Tech-Konzerne, deren Vorgehen oft als digitaler Kolonialismus bezeichnet wird. Ziel des Vortrags ist es, dieses Geflecht in den Ländern Subsahara-Afrikas zu entwirren und zu fragen, welche Möglichkeiten es für eine internationale zivilgesellschaftliche Zusammenarbeit im Sinne einer nachhaltigen Entwicklung gibt. about this event: https://fahrplan.2023.fiffkon.de/fiffkon23/talk/PCRKNY/

Ist es schon signifikant? (nook23)

Statistik ist ein wichtiger Teil moderner wissenschaftlicher Forschung. Sie hilft uns, belastbare Schlussfolgerungen aus Rohdaten zu gewinnen. Da allerdings jedes Jahr der Konkurrenzdruck im Wissenschaftsbetrieb steigt, wächst auch der Druck, mehr und mehr beeindruckende Ergebnisse zu veröffentlichen. Auch hierbei kann Statistik (bzw. ihr Missbrauch) helfen. In diesem Vortrag reisen wir durch die Wunderwelt fragwürdiger statistischer Praktiken und lernen, unsere Rohdaten so lange zu quälen, bis sie endlich jede beliebige Version unserer persönlichen Wahrheit gestehen. (Alternativ richtet sich dieser Talk auch an jeden, der ein paar Tricks zum Entdecken missbräuchlicher Verwendung von Statistik kennenlernen will.) Die Night of Open Knowledge (Nook) in Lübeck ist eine offene Vortragsveranstaltung, die einem weiten Publikum Einblicke in die verschiedene Bereiche der Informatik, aber auch technikfremde Themen bietet.

Endlich dieselbe Sprache sprechen! (nook23)

In der Sprache der Domäne erstellte Testberichte sind präzise Beschreibungen der Systemanforderungen und dienen zugleich als ausführbare Spezifikationen. Sie fungieren als lebendige Dokumentation des Systemverhaltens, erleichtern den Austausch mit der Fachabteilung und klären, ob die Implementierung den Anforderungen entspricht. JGiven ist eine leichtgewichtige Test-Bibliothek, die uns ermöglicht, unsere gewohnten Test-Werkzeuge in der IDE zu nutzen und dennoch leicht verständliche Testberichte in der Fachsprache zu erstellen. Wir müssen keine neue Syntax erlernen, sondern beschreiben die Szenarien einfach in Java. Dadurch können sie wie Produktiv-Code behandelt und mühelos angepasst werden. Nach den ersten Schritten mit JGiven+JUnit werden wir sehen, wie aus einer Menge von TestCases ein lesbarer HTML-Report generiert wird. Danach individualisieren wir den Report und erkunden die vielfältigen Optionen für datengetriebene Tests.

Eine Einführung zu CRDTs (nook23)

Es gibt Situationen in denen die typischen Ansätze zur Datenhaltung zu kurz greifen. Das ist oft vor allem dann der Fall, wenn die Daten verteilt gespeichert werden, und die Anzahl der Kopien sehr flexibel oder unbekannt ist. Dieser Vortrag möchte einen Überblick über Situationen geben, die den Einsatz von Conflict-free Replicated Data Types (CRDTs) nahelegen. Aufbauend darauf wollen wir CRDTs mit typischen Alternativen vergleichen und uns dieser Technologie anhand von Beispielen nähern.

Paying my Debt to Society: SwiftGodot (godotcon2023)

In a previous life, Miguel worked tirelessly to get Unity and other game engines to adopt .NET as a runtime to execute their game code, as it blended beauty and speed. And he dreamed that one day the pauses introduced by the garbage collector could one day be solved, but after decades this dream seems further away with each passing day. Meanwhile, a language of equal beauty and ergonomics emerged without any of these downsides. This talk will discuss both the rationale of the Swift bindings for Godot, as well as a bold proposal to integrate Swift into Godot itself. about this event: https://pretalx.c3voc.de/godotcon2023/talk/W89WUZ/
