Link Utilization
How much of a link’s capacity is consumed by an observed rate.

How much of a link’s capacity is consumed by an observed rate.
App id: NET-06. Reference version 1.0.
How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
utilization = observed / capacityInputs
| Name | Unit |
|---|---|
| Observed throughput | Mbit/s |
| Link capacity | Mbit/s |
Outputs
| Name | Unit |
|---|---|
| Utilization (hero result) | % |
| Remaining capacity | Mbit/s |
Diagnose
Observations are context. They do not pass or fail a structure. See Diagnose.
Screening bands in the app: <50% · 50–80% · 80–90% · >90%.
| When | Observation | Severity |
|---|---|---|
Utilization > 1 | Observed rate exceeds capacity | warning |
Utilization < 0.5 | Substantial capacity remains | info |
Utilization < 0.8 | Moderate/high utilization | caution |
Utilization < 0.9 | Limited headroom | caution |
Utilization ≥ 0.9 | Little spare capacity | warning |
Assumptions
- Observed rate above capacity is reported rather than clamped.
- Bands are engineering guidance, not a congestion verdict.
Provenance
- Utilization is observed rate over configured or negotiated capacity.
