Talk 1: From manual to machine: The automation revolution in internet peering.

Network operators typically negotiate BGP peering establishment via an email chain. Well-deserved attention in the past year has been given to modernising this practice in the form of the in-draft peering API rfc. Inspired by this, this talk shall cover an open-source implementation to enable widespread adoption

Talk 1: Kriten – Open-source automation platform

A demo showing how to use Kriten to run your automation code.

Kriten is a code execution platform. It is written for and runs on kubernetes as a cloud native application. Kriten exposes containerized applications written in any modern languages as no-code REST API endpoint, with local or/and AD authentication and granular RBAC it allows a requester to execute code as a kubernetes job and to get result asynchronously or synchronously.

Talk 1: Fifty ways not to do it, the history of how optical fibre communications were invented.

In 2009 the Nobel Prize committee gave the Physics prize to Charles Kao for the invention of fibre optical communications. But the story wasn’t that simple, and it didn’t have a single lone inventor. So how did we invent the idea of using glass fibres for long distance communications? And why are we returning to some of the discarded ideas?

Talk 1: Reconsidering the RPKI Trust Model and Validation Algorithm

In this talk Job Snijders from Fastly will explain how to reason about
‘trust’ in context of the RPKI, how the current validation algorithm
works, what the downsides of its rigidity are, and share perspective on
different, more robust approaches. Or, phrased in a more exciting way:
how to prepare for the theft of an RIR’s HSM?!?!

Presenter: Job Snijders (Fastly)


Talk 2: “Reclaiming” 240.0.0.0/4

In IPv4 class E space is magical, in that whenever anybody looks at it seems to have a fantastic opinion on how to reclaim it, This is becoming even more tempting in the era where IPv4 is hard to obtain and IPv6 deployment is frustratingly stubborn. In this talk I will go over the challenges and why it is probably not a good idea to try and use this dormant IPv4 space.

An overview of some of the technologies available now and coming soon. Why are there different standards and options? What do I need to look out for and what questions do I need to ask if I want to deploy these optics?

Presenter: Anthony Clarkson (Precision Optical Technologies)

Presenter: Oli Stockman


Talk 2: Fabrics

A software engineer’s view into how contemporary hardware operates and what does that mean for network and infrastructure layers, as seen in the context of machine learning hype. Fabrics, in particular non-IP fabrics, routing of address space (no, not IP address space, the real address space), Infiniband and custom transports, feeding accelerators with data and what does that mean for the networking part of the system, and how software could and does abuse the potential of underlying hardware.

Talk 1: From Network Zero to Automation Hero: A Journey in Network Automation

In this presentation I’ll explore my transformative journey in network automation over the past three years. Starting with my departure from a company lacking interest in automation and my subsequent entry into a new role with a visionary boss. Initially plagued by self-doubt and imposter syndrome, my perseverance led me to significant achievements. We implemented NetBox to manage a network inherited from multiple MSPs, paving the way for subsequent automation projects including automating core network deployments using Arista Validated Designs (AVD) and a Django-based firewall management tool called “Forge.”

These tools allowed us to model firewall rules based on device grouping, streamlining configuration and deployment processes and empowering business units by creating a self-service application named “BUG” (Business Unit Generated Firewall Rules) which enabled developers to request firewall rules easily.This journey demonstrates the transformative power of network automation and how my journey can hopefully help others to overcome challenges and drive impactful change in their organization.
