Update Network #

client.updateNetwork((networkMode: string), (config: object));

networkMode - parameter specifies what network conditions should be used. Available network configurations and networkMode parameter values can be found here or they can be accessed using constants.

config(optional) - parameter that specifies exact network conditioner field values.

Custom network configuration is taken into effect only if provided networkMode is “custom”.

Currently available custom network configuration metrics are:

Network parameter	Traffic direction	JSON key	Unit of measure	Max value
Bandwidth	Outgoing	`rate_up`	mbit
	Incoming	`rate_down`	mbit
Latency	Outgoing	`latency_up`	ms
	Incoming	`latency_down`	ms
Jitter	Outgoing	`jitter_up`	ms
	Incoming	`jitter_down`	ms
Packet loss	Outgoing	`loss_up`	%	100
	Incoming	`loss_down`	%	100

For custom network configuration jitter parameters must be defined together with latency. If jitter parameters are set without also defining latency parameters, then jitter configuration will not be applied.

The network parameters not defined in custom network configuration will be reset to their default values.
