IPGlobalStatistics.PacketReassemblyTimeout 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

获取 Internet 协议 (IP) 数据包的所有段必须到达的最长时限。

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

属性值

Int64

Int64 值，它指定数据包的所有段必须到达以免被丢弃的最大毫秒数。

属性

UnsupportedOSPlatformAttribute

示例

下面的代码示例显示 IP 数据包的重新组合统计信息。

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

注解

超过 IP 传输最大大小的数据包将分解为多个片段，并在目标处重新组合。 如果构成分段 IP 数据包的所有片段未在允许的时间内到达，则会丢弃该数据包。
