Abstract
An arrangement is provided for measuring jitter between an initiating network end point and a receiving network end point. A plurality of source packets are sent from the initiating network end point with pre-determined source spacing between any two adjacent source packets to the receiving network end point At the receiving network end point, at least some of the source packets are received with a plurality of destination spacing between pairs of adjacent received packets. A jitter estimation mechanism determines the jitter between the two network end points based on the source spacing and the destination spacing.
