Network Instability Detection

Detect Network Instability Before It Becomes a Larger Issue

RouteMon helps network teams identify BGP routing instability, route flapping, peer instability and unexpected routing behaviour that may affect connectivity or service performance. Use BGP anomaly detection and routing analytics to focus operational attention on changing network conditions.

The operational problem

Instability can develop withouta complete outage

Not every network issue begins with a link or session going down.

Repeated routing changes can create instability even when connectivity remains available.

RouteMon helps network teams identify unusual or repeated network behaviour that requires investigation.

Observed routing evidence

Surface repeatedand unexpected behaviour

Use route-flap monitoring, peer monitoring and BGP anomaly detection to focus attention on changing routing conditions.

  • Evidence 01

    Route-flap evidence

    Repeated announcements, repeated withdrawals and changing route state.

  • Evidence 02

    Prefix evidence

    Prefix instability and impact associated with repeated routing events.

  • Evidence 03

    Peer evidence

    Peers associated with repeated route changes or unstable behaviour.

  • Evidence 04

    Path evidence

    Changing paths, path anomalies and unexpected path behaviour.

  • Evidence 05

    Anomaly evidence

    Unexpected origin changes, potential route leaks or potential hijack conditions.

Evidence timeline

Investigate instabilityacross repeated events

Review recurring routing evidence to identify persistent conditions and the routes, peers, prefixes or paths involved.

  1. 01

    Repeated event appears

    An announcement, withdrawal or route change repeats.

  2. 02

    Affected route is identified

    Narrow the investigation to the associated prefix and route state.

  3. 03

    Peer and path are reviewed

    Examine peer-related instability and changing path behaviour.

  4. 04

    Condition is prioritized

    Focus operational attention on meaningful routing instability.

Expected operational value

Why instabilitydetection matters

Earlier visibility can help teams focus investigation before repeated issues go unnoticed.

  • Reduce time to investigation
  • Identify unstable peers and prefixes
  • Improve BGP troubleshooting
  • Prevent repeated issues from going unnoticed
  • Prioritize meaningful routing conditions
RouteMon / Next step

Identify routinginstability earlier.
