nog.fi meeting 2025.11nog.fi meeting

Thanks to all sponsors, volunteers, presenters and the audience!

We reminisce one of the biggest contributors to the nog.fi community.

The presentation will give an introduction to how the fibre-cable may be used as a sensor. This is for both protecting the cables, revealing any activity in node rooms, manholes or along the cable in sea (e.g. trawling), in air (fibre combined with power) or ground (e.g. digging activity).

This is an overview of ICANN's Next Round of introducing new Top Level Domains to the root zone.

This presentation is showing and discussing observations of what trends and changes can be seen after the cable cuts near the shore of Yemen. We try to highlight findings and interesting changes in routing or traffic shifts. The findings are valid globally and not just Middle East related.

As networks evolve with the adoption of edge cloud computing, artificial intelligence, and specialized processors such as Data Processing Units (DPUs), IP resource management must keep pace with these technological advancements. The traditional approaches to managing IP addresses and network configurations are increasingly inadequate in dynamic, high-performance environments where automation and scalability are key.

By leveraging real-world case studies and industry trends, this session will provide network engineers and decision-makers with actionable strategies to future-proof their IP management frameworks in a rapidly advancing digital ecosystem.

What happens when a language teacher is dropped into the deep end of the telecom industry, with zero background in fiber, DWDM, or why “it depends” is the only honest answer to anything? This talk is a personal journey of switching careers from academia and language teaching into the world of tech sales in a fast-moving, acronym-rich, and precision-driven industry.

The presentation will explore the early days of trying to sell services she barely understood, the awkward moments of miscommunication with engineers, and the hard-earned lessons of navigating between customer expectations and technical reality. It will touch on the cultural gap between sales and tech: how each side uses language differently, and how learning to "speak engineer" was just as hard as learning a foreign language.

From amusing misunderstandings to practical strategies that helped bridge the gap, this talk is for anyone who's ever had to translate between departments, roles, or mindsets.

An overview of the new RIPE Atlas visualisation tool, Khipu. I will discuss how Khipu transforms traceroute, DNS, and ping measurements into interactive network visualisations, walk through its key features (including multiple view modes and filtering capabilities), and discuss the technical architecture that enables high-performance rendering of large-scale measurement data using Vue 3 and WebGL.

A practical guide to RFC8950 - RFC 8950 provides a modern, scalable solution for carrying IPv4 traffic over an IPv6-only core network. This is a real-world problem that are actively trying to solve.

In this session, we explore a paradox at the heart of network performance: despite decades of progress in infrastructure, the application layer fails to notice.

We’ll look at this problem from the application layer perspective, and trace how design embedded in TCP, congestion control, and buffering mechanisms ignore the benefits of modern networks. The result is a global pattern of “invisible inefficiency” where improved infra delivers only theoretical gains, not visible to the software sitting atop it.

Ultimately, we have to align application layer with the physical realities of the networks that carry it. Because until we do, our infra investments will remain invisible to those who seek new use-cases and better user-experience.
