Introducing Cumulative Latency Distribution Graphs for latency testing in ByteBlower!
Posted by Mathieu Strubbe on 03 May 2021 11:54 AM
A better view on latency as ByteBlower adds Cumulative Latency Distribution Graphs for powerful, comprehensive and comparative latency insights.
It’s always been possible to perform latency tests using ByteBlower, especially now that latency is becoming more and more important, but visualising latency has always had a few difficulties:
Histograms do contain that information, but are very difficult to interpret.
As the importance of latency is increasing significantly, more research is being done on how to visualise and quantify this. An interesting approach in Low Latency DOCSIS® is one described in the whitepaper Low Latency DOCSIS: Technology Overview by CableLabs.
In this paper, a CDF or a cumulative distribution function is applied, which allows to compare two measurements, and better define pass/fail criteria. This approach is now also available in ByteBlower’s new reports!

The latency histograms fall short when you want to compare all flows. That's why we're introducing the Latency CCDF and CDF graph: In one glance it becomes clear how all flows relate to each other.
Basically: flows on the left of the CCDF graph have the lowest latency.
While low(er) latency in general is a good thing, it’s especially important in, for example, live video or video calls, gaming, all the way up to physical remote execution such as medical procedures or remotely operated vehicles or even space travel.
