Help to automate autgoing traffic limitation

Hi all, i’m using CIS from 2 month and i like it very much, but i need to find the way to limit the outgoing traffic with a script, for example a .bat file.

I exatly need to automate the execution of 2 scripts, the first (1) has to limit the outgoing traffic to 2 or 3kbps, the second (2) must restore the full bandwith.

If anyone know how i can do that…

Thanks a lot and sorry for my bad english
