Property Value

Type: System::Int64

An Int64 value that specifies the total number of packets that required fragmentation but had the "Don't Fragment" bit set.

Packets that exceed the maximum size for IP transport are broken into fragments and reassembled at the destination. The value returned by this property indicates the number of packets that needed to be fragmented for IP transport but could not be because the packet header specified that the packet not be fragmented.

The following code example displays reassembly statistics for IP packets.

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 );
}
