Summary from IETF-66 and 67: Set a LONG Loss threshold Distinguish between Long Finite Delay and Loss Avoid truncated distributions Delay of Lost Packets is UNDEFINED Maintain orthogonality – avoid double-counting defects Use conditional distributions and compute statistics Report BOTH Loss and Delay Report BOTH the Sample Mean and Median. Comparison of the Mean and Median is informative Means may be combined over time and space (when applicable) Means come with a weighting function for each sample if needed, the sample Size, and Loss simply reduces the sample size Means are more Robust to a single wonky measurement when the sample size is Large Move the Industry Away from “Average Jitter” Use the 99.9%-ile minus minimum PDV Portray this as a Delay Variation “Pseudo-Range” |
