Talk 1: AI Vibes with Panny

An exploration of frontier AI models, the Deepseek disruption, and why running AI locally matters. Live coding demos, practical tools for local models, and a look at where AI coding is heading.

Join Panny for an exploration of what’s happening in AI right now. We’ll start with live coding demonstrations using multiple AI assistants working simultaneously, then discuss the recent Deepseek moment that sent tech stocks tumbling. The talk covers why local AI matters (spoiler: access and control), tools for running open source models on your own hardware, and a look at the latest AI coding assistants. Whether you’re AI-curious or already deep in the stack, come learn about the current state of frontier models and practical tools you can use today.

Talk 1: Building Trustworthy Network Automation, From Principles to Practice

Trust is essential for successful network automation adoption.

When automation platforms exhibit predictable behaviors and transparent processes, teams can confidently delegate critical network operations. Building trustworthy automation doesn’t happen by itself, it needs to be baked into the design of every workflows.

This technical session examines core principles that build trust, including idempotency, declarative workflows, and robust version control. Using practical examples from production environments, we’ll analyze how specific technical decisions affect automation reliability and team confidence. The presentation covers key implementation patterns like state verification, diff-based changes, and failure handling. Attendees will learn concrete approaches for building automation platforms that network teams can trust and rely on daily.

Presenter: Damien Garros (OpsMill)


Talk 2: Building an open source network automation system with Nautobot

Building network automation systems using open-source tools makes automation more accessible to a wider audience, reducing barriers to adoption and enabling more flexible, adaptable solutions.

A composable, open-source automation system relies on several key components working together effectively. In this talk, I’ll explain what those components are, why they matter, and how Nautobot provides a strong foundation for building such a system.

Drawing from my experience, I’ll outline the essential building blocks—including data models, configuration management, validation, and integration with other automation tools—and explain how Nautobot’s extensibility enables it to fit seamlessly within a network automation system.

Presenter: David Groves (Nominet)


Talk 2: Some cool things I’ve found on IX LANs

bgp.tools is a route collector on 100 IXs, while these IX ports are primarily for the purpose for collecting bgp routes from route servers and exchange peers, the route collection software also collects data on the broadcast domain of the exchange.

In this talk I will go through many of the findings from this data set, explanations on what traffic probably should not be seen on internet exchange LANs, and ideas on how to improve the status quo!

OneWeb’s journey towards first packet over SR-TE , motivation and implementation using open source tools and in-house controller.

Presenter: Himan Pishnamaz (Eutelsat Oneweb)


Talk 2: Decentralising SDN

Software defined networks (SDN) introduced a number of benefits amongst them operator-specific routing, speed of innovation, and consensus-free convergence. As with all technologies, it comes with some tradeoffs — particularly introducing new dependencies and failure modes that can impact network reliability. We asked the question — can we have our SDN cake and eat it? — and discuss both our results as well as a technical direction for developing network applications.
