Definición

Espacio de nombres:

System.Net.NetworkInformation

Ensamblado:

System.Net.NetworkInformation.dll

Obtiene el número de paquetes IP (Protocolo de Internet) que no pudieron fragmentarse.

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

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

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

Public MustOverride ReadOnly Property PacketFragmentFailures As Long

Valor de propiedad

Int64

Valor Int64 que especifica el número total de paquetes que requerían fragmentación pero tenían establecido el bit "No desfragmentar".

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 );
}

}

Comentarios

Los paquetes que superan el tamaño máximo del transporte IP se dividen en fragmentos y se vuelven a ensamblar en el destino. El valor devuelto por esta propiedad indica el número de paquetes que se deben fragmentar para el transporte IP, pero no se pudo realizar porque el encabezado de paquete especificó que el paquete no se fragmenta.
