Details

Package stats summarizes round-trip samples: min, average, max, standard deviation, RFC 3550 jitter, loss and voice quality (MOS).

func Jitter(rtts []time.Duration) time.Duration

Jitter is the RFC 3550 interarrival jitter (1/16 gain).

func Loss(sent, received int) float64

Loss is the fraction of unanswered samples, clamped to [0, 1].

type Quality struct {
	R   float64
	MOS float64
}

Quality is a voice rating: R factor (0 to 100) and MOS (1 to 4.5).

func VoiceQuality(rtt, jitter time.Duration, loss float64) Quality

VoiceQuality applies the simplified ITU-T G.107 E-model. One-way delay is approximated as RTT/2: an indicator, not a measurement.

type Summary struct {
	Min, Avg, Max, StdDev time.Duration
	Jitter                time.Duration
}

Summary of the samples of one cycle.

func Summarize(rtts []time.Duration) (Summary, bool)

Summarize computes the summary of the answered samples, in order.
