属性

UnsupportedOSPlatformAttribute

例

次のコード例では、IP パケットの再構成の統計情報を表示します。

void ShowFragmentationStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Reassembly Data:" );
   Console::WriteLine( "      Reassembly Timeout .................. : {0}", 
      ipstat->PacketReassemblyTimeout );
   Console::WriteLine( "      Reassemblies Required ............... : {0}", 
      ipstat->PacketReassembliesRequired );
   Console::WriteLine( "      Packets Reassembled ................. : {0}", 
      ipstat->PacketsReassembled );
   Console::WriteLine( "      Packets Fragmented .................. : {0}", 
      ipstat->PacketsFragmented );
   Console::WriteLine( "      Fragment Failures ................... : {0}", 
      ipstat->PacketFragmentFailures );
}

public static void ShowFragmentationStatistics()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Reassembly Data:");
    Console.WriteLine("      Reassembly Timeout .................. : {0}",
        ipstat.PacketReassemblyTimeout);
    Console.WriteLine("      Reassemblies Required ............... : {0}",
        ipstat.PacketReassembliesRequired);
    Console.WriteLine("      Packets Reassembled ................. : {0}",
        ipstat.PacketsReassembled);
    Console.WriteLine("      Packets Fragmented .................. : {0}",
        ipstat.PacketsFragmented);
    Console.WriteLine("      Fragment Failures ................... : {0}",
        ipstat.PacketFragmentFailures);
}

Public Shared Sub ShowFragmentationStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Reassembly Data:")
    Console.WriteLine("      Reassembly Timeout .................. : {0}", ipstat.PacketReassemblyTimeout)
    Console.WriteLine("      Reassemblies Required ............... : {0}", ipstat.PacketReassembliesRequired)
    Console.WriteLine("      Packets Reassembled ................. : {0}", ipstat.PacketsReassembled)
    Console.WriteLine("      Packets Fragmented .................. : {0}", ipstat.PacketsFragmented)
    Console.WriteLine("      Fragment Failures ................... : {0}", ipstat.PacketFragmentFailures)

End Sub

注釈

IP トランスポートの最大サイズを超えるパケットはフラグメントに分割され、宛先で再構成されます。 フラグメント化された IP パケットを構成するすべてのフラグメントが許可時間内に到着しない場合、パケットは破棄されます。
