Overview… burstiness
By default the packets of a stream are spaced evenly in time.
The stream can be made bursty by reducing the gap between packets, and then increasing the gap between bursts to keep the rate unchanged.
This is accomplished by specifying the number of packets in each burst, and the burst density: a density of 100% means packets are transmitted back-to-back within the burst, whereas 0% means an even non-bursty spacing:
The XenaManager also calculates the spacing between packets within the burst and the spacing between bursts, and gives a simple illustration of the burst pattern.
The burstiness of a packet stream can be measured using the capture timestamps or using a histogram on the inter frame gap.
