| Metric | Definition | Unit | Example | |--------|------------|------|---------| | | Time for a packet to travel to destination and back | ms | 20 ms | | Jitter | Standard deviation or mean absolute deviation of latencies across multiple packets | ms | 5 ms | | Packet Loss | Percentage of packets never acknowledged | % | 0.1% |
Where ( D(i-1,i) ) is the difference in packet transit times between packet ( i ) and packet ( i-1 ). speed test with jitter
[ J(i) = J(i-1) + \frac - J(i-1)16 ]
