Quantifying Interference between Measurements on the RIPE Atlas - PowerPoint PPT Presentation

Quantifying Interference between Measurements on the RIPE Atlas platform Thomas Holterbach Cristel Pelsser Laurent Vanbever Randy Bush Research and Applications of Internet Measurements Saturday, 31 October 2015 Yokohama, Japan

The RIPE Atlas platform More than 8000 probes around the globe Can perform several types of measurements ➢ Ping ➢ traceroute

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

Did you experience such measurement interferences?

Did you run measurement campaigns that could have overloaded the platform? e.g full-mesh experiment
