Nokia Secures LINX London Network Core Refresh, Strengthening IXP Infrastructure for AI Era
Summary
The London Internet Exchange (LINX) has completed a refresh of its LON2 network core, selecting Nokia as the technical partner. This move finalizes LINX's dual-LAN architecture in London on Nokia's platform, aiming to provide members with a high-performance, scalable, and architecturally diverse interconnection foundation for AI workloads.
Key Takeaways
LINX's LON2 network is its secondary interconnection fabric in London, operating in parallel with the primary LON1 LAN for resilience and architectural diversity. The refresh was driven by the end-of-life of the existing technical solution.
LINX was the world's first IXP to deploy a disaggregated network using EVPN in 2018. Its LON1 network migrated to Nokia technology in 2021 due to member demand for 400GE ports. LON2 was traditionally vendor-diverse, but after PoCs, LINX decided to also migrate LON2 to Nokia, while ensuring hardware and software diversity from LON1 to meet member requirements for fully mirrored redundant infrastructure.
Nokia highlighted that as AI becomes the dominant workload shaping modern networks, service providers and critical infrastructure operators need platforms ready for new traffic patterns, higher performance, and greater scale.

Why It Matters
This signals that critical Internet Exchange Point (IXP) infrastructure is undergoing consolidated upgrades and vendor consolidation for the AI era. The control layer is concentrating towards single platform vendors capable of delivering high performance, programmability, and scale, potentially impacting the architectural resilience and technology roadmap choices of future internet backbones....
