Resilience

Resilience includes high availability, disaster recovery, continuity, alternate routing, carrier diversity, power, monitoring and human runbooks. These are related but not interchangeable.

What it does

Resilience keeps emergency communications working through failures, disasters and degraded conditions.

Resilience keeps the emergency path usable when systems, sites or networks fail.

How it works

  • Uses redundant paths and functions.
  • Routes around failed PSAPs or network elements.
  • Combines technical monitoring with operational decision-making.

Key interfaces and protocols

  • Failover routing
  • Monitoring
  • DNS/service discovery
  • Power/site redundancy
  • Runbooks

Systems it interacts with

  • Failover and alternate routing
  • ESInet
  • ESRP
  • PSAP
  • Testing

Common failure modes

  • Redundant systems share one dependency.
  • Disaster recovery exists but is not rehearsed.
  • Alternate route lacks location or media support.
  • Monitoring detects failure after callers are impacted.

Implementation considerations

  • Separate high availability from disaster recovery.
  • Exercise regional outage and PSAP evacuation scenarios.
  • Measure recovery against emergency service objectives.

Standards

  • ETSI TS 103 480
  • Operational continuity practices
