Case Study: CN (Canadian National Railway) achieves reliable network performance and faster troubleshooting with NETSCOUT nGenius

CN Keeps Trains and Network Operating Efficiently Using NETSCOUT Solutions

CN, one of North America's largest railroads with a 19,200‑mile network and over 22,000 employees, depends on a highly responsive WAN to support real‑time shipment tracking, automated rail systems and critical business applications. The company was facing intermittent application slowdowns and response‑time delays across thousands of switches and endpoints but couldn’t pinpoint the root causes.

By deploying NETSCOUT nGenius appliances and Intelligent Data Sources with one‑minute granularity and packet‑level analysis, CN quickly identified causes such as non‑business bandwidth usage and mass desktop upgrades, diagnosed drive‑mapping timeouts, and validated QoS/VoIP behavior. The solution shortened resolution times, enabled accurate capacity planning and collaborative application rollouts, and reduced performance incidents while ensuring mission‑critical services remained prioritized.
