A method of estimating end-to-end delay performance at an end-to-end delay percentile of interest for a network having two or more network segments includes measuring a delay performance level for each network segment at a corresponding network segment delay percentile and concatenating the measured performance levels by summing to provide an estimate value indicative of end-to-end delay performance. A network segment delay percentile may be selected for each network segment for a particular end-to-end delay percentile of interest, error band, and number of segments. Selection may result in using the same network segment delay percentile for all network segments, or, selecting individual network segment delay percentiles for each network segments, or selecting a first network segment delay percentile for a particular network segment having a largest range of delay relative to the other network segments and selecting a second network segment delay percentile for other segments.
