Functions

func Start 

func Start(targetPort string, profileName string) (int, func(), error)

Start spins up a local TCP proxy that introduces traffic shaping (latency, jitter, bandwidth limits) before forwarding the traffic to the destination port. Returns the allocated local port, a cleanup closure, and any error.

Types

type Profile 

type Profile struct {
	Latency    time.Duration
	Jitter     time.Duration
	Bandwidth  int     // bytes per second
	PacketLoss float64 // probability 0.0 to 1.0
}

Profile maps named network profiles to actual constraints
