17. Autonomous System Provider Authorisation

Alastair Strachan (RIPE NCC)

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...

5. Building a National NOG Community

Mx Keith Mitchell (SMOTI)

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...

13. Evaluation of BGP Roles (RFC 9234) with the aid of an AI Assistant

Dr Julian Lucek (HPE)

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).

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

Steve Jones (Huber+Suhner)

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

22. NetUK Update

Dave Pumford (PTX Technologies / NetUK)

Main Session

Standard Presentation

Updates about NetUK including the finances

21. NetUK Welcome

Dave Pumford (PTX Technologies / NetUK), Matt Jepp (SG.GS / NetUK)

Main Session

Standard Presentation

Welcome to NetUK3!

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

Kevin Meynell (SCION Association)

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...

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

Gerhard Stein (Lead Research Engineer)

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...

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

Ritesh Mukherjee (Nokia)

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...
