Unity - Scripting API:

public ConnectionSimulatorConfig(outMinDelay: int, outAvgDelay: int, inMinDelay: int, inAvgDelay: int, packetLossPercentage: float)

Parameters

outMinDelay	Minimal simulation delay for outgoing traffic in ms.
outAvgDelay	Average simulation delay for outgoing traffic in ms.
inMinDelay	Minimal simulation delay for incoming traffic in ms.
inAvgDelay	Average simulation delay for incoming traffic in ms.
packetLossPercentage	Probability of packet loss 0 <= p <= 1.

Will create object describing network simulation parameters.
