About
This Packet Loss & Jitter Tester is a precision diagnostic tool designed to evaluate the stability of your internet connection, not just its speed. While standard speed tests measure bandwidth (capacity), this tool measures quality (reliability). High bandwidth means nothing if data packets are dropped or arrive irregularly.
Why this matters: In real-time applications like Online Gaming (CS:GO, Valorant) or VoIP (Zoom, Discord), consistency is king. Packet Loss occurs when data fails to reach its destination, causing rubber-banding or robotic audio. Jitter is the variance in latency; a ping that spikes from 20ms to 150ms creates a stuttery experience even if the average is low.
This tool simulates high-frequency traffic to detect micro-outages and strictly analyzes UDP/TCP reliability against industry standards for different use cases.
Formulas
We calculate Jitter (J) using the RFC 3550 smoothing algorithm, which approximates the statistical variance of packet inter-arrival times. This is more accurate for real-time streams than simple standard deviation.
Packet Loss Percentage (L) is strictly defined as:
Where a packet is considered "Lost" if latency > Thresholdtimeout (default 1000ms).
Reference Data
| Metric | Excellent (Esports/Comp) | Good (Casual Gaming) | Fair (Browsing/Streaming) | Poor (Unusable) |
|---|---|---|---|---|
| Packet Loss | 0.0% | < 1.0% | 1.0 - 2.5% | > 2.5% |
| Jitter | < 1ms | < 5ms | < 30ms | > 50ms |
| Latency (Ping) | < 20ms | < 50ms | < 100ms | > 150ms |
| MOS Score | 4.5 - 5.0 | 4.0 - 4.4 | 3.0 - 3.9 | < 3.0 |
