The October 2025 Nokia data center fabric reliability study presents a comprehensive assessment of reliability in modern data center networks, offering clear evidence that next-generation network operations and automation tooling can deliver significant improvements in uptime, operational resilience, and financial performance.

Conducted in collaboration with Nokia Bell Labs Consulting, the study quantifies how advanced data center switching architectures built on Nokia SR Linux network operating system (NOS) and Event-Driven Automation (EDA) platform dramatically outperform traditional, siloed legacy data center solutions.

This whitepaper assesses reliability in modern data center networks, comparing traditional "Present Mode of Operation" (PMO) legacy solutions against "Future Mode of Operation" (FMO) next-generation architectures.
