查询/更改NIC以编程方式接收描述符? [英] query / change NIC receive descriptors programmatically?

问题描述

我有一个应用程序可以接收非常大的网络流量.为了正常工作，NIC必须将其"RX描述符"缓冲区的大小增加到Windows/NIC(相对保守的默认值)之上.我可以通过设备管理器(网络适配器->< nic_name>->高级)为每个系统手动更改它，但是随着我们构建越来越多的这些系统，这确实容易出现人为错误.
有什么方法可以从我们的C ++应用程序中(最低)查询当前设置，或者从我们的应用程序中(最佳)自动设置吗?

在此先感谢您.

I''ve got an application that receives very heavy network traffic. To work properly, the NIC must have its "RX Descriptors" buffer size increased above the Windows/NIC rather conservative default. I can change it manually for each system through the Device Manager (Network Adapters -> <nic_name> -> Advanced), but that is really prone to human error as we build more and more of these systems.

Is there any way to (minimally) query the current setting from within our C++ application, or (optimally) set it automatically from within our application?

Thanks in advance.

推荐答案

查看INetCFG接口

如果那不能解决问题，我认为您唯一的选择是尝试从内核模式更改此设置. (通过驱动程序)

同样，我也不认为这是一个好方法，因为您所做的更改会影响整个系统
不仅是您的应用程序.

Look into the INetCFG interface

http://msdn.microsoft.com/en-us/library/ff547694.aspx[^]

if that doesn''t do the trick i think your only other option is to try and change this setting from kernel mode. (through a driver)

Also i do not believe this is a good approach since the changes you are making will affect the entire system
not just your application.

太好了-谢谢库尔特！我将看一下此链接，看看是否可以解决问题.

我理解并感谢您的关注，但是这些设备实际上是简化了OEM嵌入式"控制器的，这些控制器在集成到较大系统中的专用定制硬件上运行.他们没有头，除非运行我们的软件，否则将永远看不到曙光".所以我们应该很安全.

Great - thank you Kurt! I''ll take a look at this link and see if that will do the trick.

I understand and appreciate your concern, but these boxes are actually stripped down OEM "embedded" controllers running on dedicated custom hardware integrated into a larger system. They are headless, and will never "see the light of day" except to run our software. So we should be safe.
