Case Study: U.S.-Based Airport achieves 2-hour identification of month-long latency and protects passenger services with NETSCOUT

Airport IT Quickly Identifies Performance Issues Impacting Travelers

A major U.S. airport that handles about 400,000 flights and 40 million passengers annually was experiencing recurring performance problems across critical services—most notably a month‑long latency issue affecting the parking payment application. The IT team lacked end‑to‑end visibility across the campus network, forcing time‑consuming, often physical troubleshooting and leaving them unable to prove whether problems were network‑related.

By deploying NETSCOUT’s nGeniusONE with InfiniStreamNG appliances and nGenius Packet Flow Switches to capture and analyze DPI “smart data,” the team pinpointed the parking app latency to a credit‑card gateway located in Asia within two hours, corrected the routing, and uncovered obsolete protocols and expired certificates. The deployment delivered faster MTTR, proactive monitoring, custom dashboards and reports, and protection of passenger experience and revenue.
