  2. Packets Delay variation (PDV) is the difference end to end one way delay between selected packets in a flow with any lost packets being ignored. The effect is sometimes referred to as jitter, although the definition is an imprecise(inexact) fit. jitter is  a metric (a system or standard of measurement) that describes the level of disturbance of packet arrival times with respect to an "ideal“ pattern. Such disturbances can be caused by competing traffic, or by contention on processing resources in the network.

  3. E.x of packets delay variation • Jitter might be part of calculating the quality of service. This is not limited to VOIP (technology that allows telephone calls to be made over computer networks like the Internet.) but also for streaming video/audio for instance. • One of the examples that you could basically use jitter (and of course other parameters) to get an early warning of worsening service quality. If you compare the measured jitter with the current server load, it might be possible to indicate even DDOS attacks(multiple compromised systems usually infected with a Trojan are used to target a single system causing a Denial of Service (DoS) attack)or other developing problems.
