Interference between measurements Impact:
- Reported delays measured by or towards the probe
➢ Shifts in the RTT ➢ Increased standard deviation, 95th percentile, ..
- Measurements' completion time
➢ Increases when the probe is loaded
- V3 probes mitigate the impact

Did you experience such measurement interferences?
SLIDE 11
Did you run measurement campaigns that could have overloaded the platform? e.g full-mesh experiment
