===== Discussion =====

Jitter refers to variation in packet delay across a network path.

In the context of [[dido:99_annexes:annex-b-terms-and-definitions:i:internet_qos]], Jitter affects traffic that depends on regular packet delivery, including voice, video, telemetry, and time-sensitive operational observations.

===== Definition =====

//variation in network delay experienced by packets in a packet stream//

===== Source =====

Generalised from Internet QoS terminology and IP packet delay variation terminology.

===== Note =====

Jitter is not latency itself. Latency describes delay. Jitter describes variation in delay.

===== Example =====

A stream with stable latency has low jitter. A stream with rapidly changing delay has high jitter.
