Resilient Timing for Critical National Infrastructure

Critical infrastructure requires precise timing to operate. This reliance makes the infrastructure vulnerable to disruptions in timing that can be either intentional or unintentional. Intentional disruptions can be caused by GNSS jamming or spoofing or network attacks.. Unintentional disruptions are usually caused by equipment failures or acts of nature.

Back in April 2022, Alliance for Telecommunications Industry Solutions (ATIS) hosted a webinar on this topic, a precursor to the Annual Workshop on Synchronization and Timing Systems (WSTS). The webinar featured top industry experts delivering insight into the latest techniques for adding resilience and robustness to timing infrastructure. It covered the most critical topics in timing resilience, including:

  • Redundancy
  • Holdover
  • Management
  • Monitoring
  • Alternative reference time sources

Examples address networks used for critical industry applications such as:

  • Power grids
  • Telecommunications
  • Finance systems
  • Broadcast/media
