TcpStatistics.MinimumTransmissionTimeout Property

Gets the minimum retransmission time-out value for Transmission Control Protocol (TCP) segments.

Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

public abstract long MinimumTransmissionTimeout { get; }

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 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 static void ShowTcpTimeouts()
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    TcpStatistics tcpstat = properties.GetTcpIPv4Statistics();

    Console.WriteLine("  Minimum Transmission Timeout............. : {0}", 
    Console.WriteLine("  Maximum Transmission Timeout............. : {0}", 
    Console.WriteLine("  Maximum connections ............. : {0}", 
void ShowTcpTimeouts()
    IPGlobalProperties* properties = IPGlobalProperties::GetIPGlobalProperties();
    TcpStatistics* tcpstat = properties->GetTcpIPv4Statistics();

    Console::WriteLine(S"  Minimum Transmission Timeout............. : {0}", __box(tcpstat->MinimumTransmissionTimeOut));
    Console::WriteLine(S"  Maximum Transmission Timeout............. : {0}", __box(tcpstat->MaximumTransmissionTimeOut));
    Console::WriteLine(S"  Maximum connections ............. : {0}", __box(tcpstat->MaximumConnections));
