Experiment conclusions
Backbone baseline jitter is < 1 ms
- Congestion is not the problem we need to solve!
Many events > 1ms can be eliminated
- ISPs building with 1/10G ethernet should be concerned about ARP cache timeout
ISPs: need to revisit routing timer settings
- Operational emergencies led to high timer settings
- Software changes may have eliminated the need
Protocol designers: more robust timers
