Forwarding performance during routing instability

• Route flaps
  • Forwarding table entries not used for data forwarding are dynamically changed
  • Forces router to continuously recalculate and rebuild forwarding tables
  • Useful for benchmarking effect on forwarding performance of routers
• Route convergence
  • Measures the effect on traffic forwarded by a router when routes change
  • Measure packet loss, and time for packets to be directed to another interface
