Streaming Stability Score (SSS) v1.0
A reproducible scoring method for estimating how suitable a network connection is for stable video streaming. The score ranges from 0 to 100 and combines bandwidth headroom, latency, jitter and packet loss.

How SSS v1.0 works
The final score is a weighted combination of four component scores:
| Component | Weight |
|---|---|
| Bandwidth headroom | 40% |
| Latency | 20% |
| Jitter | 20% |
| Packet loss | 20% |
SSS = round(0.40 × bandwidth + 0.20 × latency + 0.20 × jitter + 0.20 × packet loss)
SSS is a heuristic for educational and troubleshooting use. It is not an industry standard and does not guarantee the performance of any streaming service.
Interpretation
| 90–100 | Excellent |
| 75–89 | Good |
| 60–74 | Moderate |
| 40–59 | Weak |
| 0–39 | Poor |
