Jitter

Go up to Terms and Definitions

Discussion

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

In the context of 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.
