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.
Types ¶
type Network ¶
type Network interface {
Adapter(tnet.Identity, ...bsnet.NetOpt) bsnet.BitSwapNetwork
HasPeer(peer.ID) bool
}
Network is an interface for generating bitswap network interfaces based on a test network.
func RateLimitedVirtualNetwork ¶
func RateLimitedVirtualNetwork(d delay.D, rateLimitGenerator RateLimitGenerator) Network
RateLimitedVirtualNetwork generates a testnet instance where nodes are rate limited in the upload/download speed.
func VirtualNetwork ¶
VirtualNetwork generates a new testnet instance - a fake network that is used to simulate sending messages.
type RateLimitGenerator ¶
type RateLimitGenerator interface {
NextRateLimit() float64
}
RateLimitGenerator is an interface for generating rate limits across peers
func FixedRateLimitGenerator ¶
func FixedRateLimitGenerator(rateLimit float64) RateLimitGenerator
FixedRateLimitGenerator returns a rate limit generatoe that always generates the specified rate limit in bytes/sec.
func VariableRateLimitGenerator ¶
func VariableRateLimitGenerator(rateLimit float64, std float64, rng *rand.Rand) RateLimitGenerator
VariableRateLimitGenerator makes rate limites that following a normal distribution.
