Limit network speed on all computers

I want to create program in C#.NET to limit network speed on all computers开发者_开发技巧..any idea?

Not really possible as that would require you to write a new driver, as the .net framework is too high level to have access to such interfaces.

Sheng, if you would like to sniff what is on the network, you may be able to do it with C# and pinvoke, you can have a look here:

or at sys internals's TCPView just to get inspired...
