Public MustOverride ReadOnly Property MinimumTransmissionTimeout As Long

Property Value

Type: System.Int64
An Int64 value that specifies the minimum number of milliseconds permitted by a TCP implementation for the retransmission time-out value.

TCP starts a retransmission timer when each outbound segment is passed to the network layer (IP). If no acknowledgement is received for the data in the segment before the timer expires, the segment is retransmitted. The timer The timer can be set to any value between the MinimumTransmissionTimeOut value and the MaximumTransmissionTimeOut value.

The following code example displays time-out and maximum connection information.

Public Shared Sub ShowTcpTimeouts() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim tcpstat As TcpStatistics = properties.GetTcpIPv4Statistics()

    Console.WriteLine("  Minimum Transmission Timeout............. : {0}", tcpstat.MinimumTransmissionTimeout)
    Console.WriteLine("  Maximum Transmission Timeout............. : {0}", tcpstat.MaximumTransmissionTimeout)
    Console.WriteLine("  Maximum connections ............. : {0}", tcpstat.MaximumConnections)

End Sub 'ShowTcpTimeouts
