Network Jitter
Definition
Network jitter describes fluctuating transit times of successive data packets.
The temporal variation of delay of successive data packets.
Simply explained
Data does not arrive evenly but sometimes faster and sometimes slower.
Why it matters in practice
Helps develop and operate digital systems robustly, securely, and maintainably.
Example from business
A voice call has low average latency but audible dropouts due to strongly fluctuating packet transit times.
Limits and pitfalls
- Equating jitter with latency or packet loss and considering only averages.
Origin & history
The IETF standardized measurement terms for packet delay variation, especially for real-time traffic.
Use in mid-sized companies
- Possible example: A voice call has low average latency but audible dropouts due to strongly fluctuating packet transit times.
