Latency / Jitter

Min, max, average, median, and successive-sample jitter from ping-style timings.

Networking & Communications

Min, max, average, median, and successive-sample jitter from ping-style timings.

App id: NET-08. Reference version 1.0.

How to fill it

Add rows as you need them. The tool uses every row you enter.

On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Formula

jitter = average(|L[i] − L[i−1]|)

Inputs

Name	Unit
Latency sample	`ms`

Outputs

Name	Unit
Average latency (hero result)	`ms`
Minimum latency	`ms`
Maximum latency	`ms`
Median latency	`ms`
Latency spread	`ms`
Jitter estimate	`ms`

Diagnose

Observations are context. They do not pass or fail a structure. See Diagnose.

Screening bands in the app: Low · Moderate · High.

When	Observation	Severity
`ms < 20`	Low latency	info
`ms < 100`	Moderate latency	info
`ms ≥ 100`	High latency	caution
`Jitter estimate < 0 or not Average latency > 0 and Jitter estimate = 0`	Low variation	info
`ratio < 0.1`	Low variation	info
`ratio < 0.3`	Moderate variation	caution
`ratio ≥ 0.3`	High variation	warning

Assumptions

Enter samples in order. Jitter is the average of |Δ| between successive samples.
Latency bands are application-dependent context, not a universal limit.

Provenance

Field jitter is mean successive absolute difference, not a telecom jitter model.
