Windows 2012 R2和TCP慢启动和超v主机
提问于 2015-11-24 08:57:28
我需要更改TCP InitialCongestionWindow的默认值。
我看了这份文件：https://www.iispeed.com/blog/windows-server-2012-and-tcp-slow-start
我在超视距托管的2012年虚拟服务器R2上试用了它。
PS C:\>Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionProvider CTCP我有错误：
Set-NetTCPSetting : No MSFT_NetTCPSetting objects found with property 'SettingName' equal to 'Custom'. Verify the valu
e of the property and retry.
At line:1 char:1
+ Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionPro ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (Custom:String) [Set-NetTCPSetting], CimJobException
+ FullyQualifiedErrorId : CmdletizationQuery_NotFound_SettingName,Set-NetTCPSetting问题是，我如何才能理解IISspeed文档所告诉的内容呢？如果我在超级v机上改变这个，我是否也需要在超级主机上改变这个，以使实际情况有所改变？
我是否应该对SSL端口443做同样的更改？
我执行了这个命令：

您需要首先创建传输过滤器，它将TCP设置指定为NetTcpSetting对象，如下面的示例所示。
New-NetTransportFilter -SettingName Custom -LocalPortStart 80 -LocalPortEnd 80 -RemotePortStart 0 -RemotePortEnd 65535当您想要修改设置时，将使用Set-NetTCPSetting命令。因此，您为什么要接收有关未找到的自定义对象的错误。在创建传输筛选器之后，您的原始命令应该可以修改设置。

嗨，我在运行时遇到了同样的错误：
PS C:\Windows\system32> Get-NetTransportFilter
SettingName : Automatic
Protocol : TCP
LocalPortStart : 0
LocalPortEnd : 65535
RemotePortStart : 0
RemotePortEnd : 65535
DestinationPrefix : *
SettingName : DatacenterCustom
Protocol : TCP
LocalPortStart : 80
LocalPortEnd : 80
RemotePortStart : 0
RemotePortEnd : 65535
DestinationPrefix : *换句话说，端口80 (DataCenterCustom)和其他端口(自动)已经有了一个过滤器，出于某种原因，我没有编辑的权限(我是域网络的一部分，我不在主节点中)。
我所做的是更改Set-NetTCPSetting中过滤器的名称，运行第二部分：
Set-NetTCPSetting -SettingName DatacenterCustom -InitialCongestionWindow 10 -CongestionProvider CTCP 这就是全部，现在就是工作了
