Functions ¶
func InternetLatencyDelayGenerator ¶
func InternetLatencyDelayGenerator( mediumDelay time.Duration, largeDelay time.Duration, percentMedium float64, percentLarge float64, std time.Duration, rng *rand.Rand) delay.Generator
InternetLatencyDelayGenerator generates three clusters of delays, typical of the type of peers you would encounter on the interenet. Given a base delay time T, the wait time generated will be either: 1. A normalized distribution around the base time 2. A normalized distribution around the base time plus a "medium" delay 3. A normalized distribution around the base time plus a "large" delay The size of the medium & large delays are determined when the generator is constructed, as well as the relative percentages with which delays fall into each of the three different clusters, and the standard deviation for the normalized distribution. This can be used to generate a number of scenarios typical of latency distribution among peers on the internet.
