<# .SYNOPSIS Starts a bandwidth test over the internet or on the local private network. .DESCRIPTION Starts a bandwidth test with iPerf3 over the internet against a public iPerf3 server, or on the local private network against a previously-configured iPerf3 server. .PARAMETER Internet Forces the bandwitdth test to run over the internet against a public iPerf3 server. If a default public iPerf3 server is not specified in the configuration file, the user will be prompted to run Set-SpeedTestConfig. .PARAMETER Local Forces the bandwidth test to run over the local network against a locally-accessible iPerf3 server. If a default server is not specified in the configuration file, the user will be prompted to run Set-SpeedTestConfig. .PARAMETER Server The hostname or IP address of a server that is running iPerf3 as a listening service. .PARAMETER Port The port on the iPerf3 server that iPerf3 is listening on. This will run the local iPerf3 client on the same port as they must match on the client and the server. If Server is specified and Port is not, the default port '5201' will be used. .EXAMPLE Invoke-SpeedTest -Internet Runs a bandwidth test against default public iPerf3 server that is stored in the configuration. If there is no stored default, you will be prompted to set one. .EXAMPLE Invoke-SpeedTest -Local Runs a bandwidth test against default local iPerf3 server that is stored in the configuration. If there is no stored default, you will be prompted to set one. .EXAMPLE Invoke-SpeedTest -Server local.domain.com Runs a bandwidth test against iPerf3 server 'local.domain.com' on default port '5201'. .EXAMPLE Invoke-SpeedTest -Server 20.19.57.21 -Port 7777 Runs a bandwidth test against iPerf3 server '20.19.57.21' on port '7777'. #> function Invoke-SpeedTest { [CmdletBinding()] Param ( [Parameter(ParameterSetName="Internet")] [Switch] $Internet, [Parameter(ParameterSetName="Local")] [Switch] $Local, [Parameter(Mandatory=$true, ParameterSetName="Specified")] [ValidateNotNullOrEmpty()] [String] $Server, [Parameter(ParameterSetName="Specified")] [ValidateNotNullOrEmpty()] [String] $Port ) Write-Verbose -Message "Starting speed test."
