IPGlobalStatistics.PacketReassemblyTimeout Propiedad

Definición

Espacio de nombres:

System.Net.NetworkInformation

Ensamblado:

System.Net.NetworkInformation.dll

Obtiene el intervalo máximo de tiempo en el que deben llegar todos los fragmentos de un paquete IP (Protocolo de Internet).

public:
 abstract property long PacketReassemblyTimeout { long get(); };

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract long PacketReassemblyTimeout { get; }

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.PacketReassemblyTimeout : int64

Public MustOverride ReadOnly Property PacketReassemblyTimeout As Long

Valor de propiedad

Int64

Valor Int64 que especifica el número máximo de milisegundos que deben tardar en llegar todos los fragmentos de un paquete para evitar que se descarte.

Atributos

UnsupportedOSPlatformAttribute

Ejemplos

En el ejemplo de código siguiente se muestran las estadísticas de reaensamblaje de los paquetes IP.

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 );
}

        ipstat.PacketsFragmented);
    Console.WriteLine("      Fragment Failures ................... : {0}",
        ipstat.PacketFragmentFailures);
}

Comentarios

Los paquetes que superan el tamaño máximo del transporte IP se dividen en fragmentos y se vuelven a ensamblar en el destino. Si todos los fragmentos que componen un paquete IP fragmentado no llegan dentro del tiempo permitido, el paquete se descarta.
