Example Data Table
| Link | Avg Latency (ms) | Min (ms) | Max (ms) | Std. Dev. (ms) | Packets Sent | Packets Received | Late Packets |
|---|---|---|---|---|---|---|---|
| Branch MPLS | 24 | 18 | 37 | 4.1 | 8000 | 7988 | 66 |
| Voice Gateway | 31 | 21 | 58 | 7.3 | 12500 | 12340 | 295 |
| Video Uplink | 42 | 25 | 79 | 10.8 | 15000 | 14720 | 520 |
Formula Used
- Peak-to-Peak Jitter = Maximum Latency − Minimum Latency
- Normalized Jitter (%) = (Latency Standard Deviation ÷ Average Latency) × 100
- Packet Loss (%) = ((Packets Sent − Packets Received) ÷ Packets Sent) × 100
- Late Packet Ratio (%) = (Late Packets ÷ Packets Received) × 100
- Stability Index = 100 − weighted penalties from jitter, loss, late packets, and out-of-order packets
- Quality Score = 100 − weighted impact of normalized jitter, packet loss, and late delivery ratios
This tool combines direct jitter measurements with delivery quality indicators. That gives a broader network experience view for voice, video, and interactive traffic.
How to Use This Calculator
- Enter the monitored link name so exported reports stay easy to identify.
- Add average, minimum, and maximum latency values from your monitoring system.
- Input the latency standard deviation to represent delay spread across samples.
- Provide packet counts, including sent, received, late, and out-of-order packets.
- Set a jitter threshold that matches your service quality target.
- Click Measure Jitter to display results above the form.
- Use the CSV and PDF buttons to save the analysis for audits or reporting.
