4. When UK Traffic Takes an Unplanned Detour: Routing Security for the UK Peering Community

Ritesh Mukherjee (Nokia)

06/07/2026, 13:15

Main Session

Standard Presentation

In June 2019, a Swiss data center accidentally leaked over 70,000 routes to China Telecom in Frankfurt. Within minutes, China Telecom announced those routes globally, and for over two hours, massive volumes of European mobile traffic — destined for networks in the Netherlands, Switzerland, and France — were silently rerouted through Chinese state-controlled infrastructure. In the summer of...

10. Understanding and optimising transceiver efficiency using internal metrics for improved power savings

Gerhard Stein (Flexoptix)

06/07/2026, 13:45

Main Session

Standard Presentation

In high-performance optical communication systems transceiver health and efficiency are critical to network reliability and energy consumption. This presentation explores the powerful capabilities of Versatile Diagnostics Monitoring (VDM) features found in modern optical transceivers (beyond the speed of 100G) with a particular focus on the Thermoelectric Cooler (TEC) current metrics. By...

31. Data Signal-Based Distributed Fibre Optic Sensing

Jasmine Parkes (Comtek Network Systems and Bangor University)

06/07/2026, 14:15

Main Session

Standard Presentation

Physical fibre cable problems cause roughly a third of all network outages. Reducing Mean Time to Repair (MTTR) isn’t just a technical goal-it’s an economic necessity. While Distributed Fibre Optic Sensing (DFOS) can solve this, the high cost of deploying dedicated sensing fibres or extra lasers remains a major obstacle for widespread operator adoption.

To solve this, our joint R&D...

6. Hollow Core Fibre - Nothing is better than glass for guiding light

Steve Jones (Huber+Suhner)

06/07/2026, 14:50

Main Session

Standard Presentation

The impressive advantages when using light not silicon make the promise of HCF something worth taking notice of.
This presentation takes a short look at the technology behind HCF, outlines the benefits and possible applications whilst highlighting some constraints (& solutions) in market dominated with singlemode fibre & LC/APC connections

11. Data Centers in Space - The Big Picture

Geoff Bennett (Nokia)

06/07/2026, 15:50

Main Session

Standard Presentation

Data Centers in Space
Geoff Bennett
Director, Solutions and Technology, Nokia

The race for companies to develop the next best Artificial Intelligence model means that they need to deploy processing capacity at unprecedented scale. We are already seeing the construction of multi-gigawatt scale data centers, and this creates significant challenges to find sufficient space, power and fresh...

24. Telecoms Inventory for GPON using Kuwaiba

Mr Corey Maltby (Solent University), Craig Gallen (Entimoss and Solent University), Mr Oliver Myers (Solent University)

06/07/2026, 16:20

Main Session

Standard Presentation

[Kuwaiba][1] is an open source telecoms inventory solution which originated in South America but is increasingly gathering attention from service providers globally. It provides the power of many commercial systems which model network physical and logical resources and services at a significantly lower cost.
Recently a group of students from Solent University did an industrial consulting...

25. Edge Network Evolution

Ben Ryall (Meta)

06/07/2026, 16:35

Main Session

Standard Presentation

This short talk outlines how Meta's edge infrastructure is evolving to meet the demands of changing workloads — from traditional content delivery to emerging AI-driven experiences. The speaker explains how Meta's network topology is being reshaped to solve for both efficiency and quality of experience, ensuring that networks of all sizes continue to have access to direct, 1:1 peering...

29. Which in my switch? LPO, CPO, XPO optics. What are they, when to use

Dr Robert Friskney (Arista)

06/07/2026, 17:05

Main Session

Standard Presentation

I will first detail what LPO (linear-drive pluggable optics) are versus traditional pluggables, and contrast CPO (co-packaged optics) with this, and their respective practical benefits such as cost, latency, power. I will talk about switch/routing use-cases where LPO wins over traditional pluggables today and vice versa - plus how this will evolve as port data-rates increase. Then I will talk...

23. LON2 Network Refresh

Jan Kayser (LINX), Megan Atkins (LINX)

07/07/2026, 10:00

Main Session

Standard Presentation

LON2 was originally launched in 2002 following LON1’s increasing popularity and was created to ensure there was no critical single point of failure in the UK’s internet connectivity. LINX’s dual LAN infrastructure design in London has been something that sets us apart over the years from other Internet Exchange Points. Operating a redundant, diverse and resilient solution in house for members...

3. SCION: Secure Path-Aware Internet Routing for Critical Infrastructures

Kevin Meynell (SCION Association)

07/07/2026, 10:30

Main Session

Standard Presentation

The Internet routing system (BGP) is rarely considered when discussing cybersecurity even though this remains an insecure aspect of the network and is increasingly used as an attack vector. Even though measures such as RPKI have been developed in recent years to improve routing security, adoption has been limited and still do not address the fundamental issue of limited control over where data...

1. Engaging with PeeringDB's Product Committee

Leo Vegoda

07/07/2026, 11:00

Lightning Talks

Standard Presentation

PeeringDB is both a directory of interconnection opportunities and an API enabling automation. Decisions on which features should be developed, improved, or changed sits with its volunteer Product Committee. But the Product Committee relies on PeeringDB's users to inform its decisions.

This presentation will explain how and why to engage with the Product Committee. Attendees will then be...

26. Rethinking Network Monitoring

Mr David Flores

07/07/2026, 11:45

Main Session

Standard Presentation

Traditional network monitoring — SNMP polling, static dashboards — tells us what broke, not why. This talk reframes monitoring as an observability problem and walks through a modular, open-source stack enriched with a source of truth. We'll cover correlating metrics, logs and flows, event-driven automation, and AI-assisted root cause analysis — so you leave with a practical blueprint you can...

17. Autonomous System Provider Authorisation

Ralph Smit (RIPE NCC)

07/07/2026, 12:15

Main Session

Standard Presentation

ASPA stands for Autonomous System Provider Authorisation and is a relatively new type of object standardised in the RPKI ecosystem. ASPA objects are signed by AS owners and allow an AS to declare its authorised upstream providers, which prevents route leaks, BGP path spoofing, and valley-free routing violations. They can be created in the hosted RPKI systems of ARIN and RIPE NCC, or using...

2. The Network Automation Forum Framework: A vendor-neutral reference model for building automation at scale

Pete Crocker (OpsMill)

07/07/2026, 12:45

Main Session

Standard Presentation

The Network Automation Forum spent the last year developing a common reference architecture that network engineers, vendors, consultants, and end-users can actually use.

This talk walks through the framework architecture, explains why we needed standardised language around network automation, and shows how you can apply it whether you're starting from scratch or trying to make sense of...

5. Building a National NOG Community

Mx Keith Mitchell (SMOTI)

07/07/2026, 14:35

Main Session

Standard Presentation

netUK's predecessor organisation, the United Kingdom Network Operators' Forum (UKNOF), ran over 50 conferences and operated community platforms for British Internet infrastructure providers and professionals between 2005 and 2023.

This talk, by UKNOF's founder, is a retrospective of that time, from UKNOF's early volunteer high-energy ad-hoc formation, through its growth and success, to one...

Dr Julian Lucek (HPE)

07/07/2026, 16:00

Main Session

Standard Presentation

LLMs have greatly improved recently with the advent of reasoning models. We will set the scene by showing the results of LLM benchmarking tests against networking certification exams. We will then show an example in which an LLM, in conjunction with a Junos MCP server, configures, tests and documents BGP Roles (RFC 9234).
