How Bandwidth limiting is working?

Question

hi friends,

         If you see the famous FTP Application like Filezilla and Aspera

they are intelligently using the bandwidth resources.For example flashget

also has an option to download a file at particular bandwidth rate.

how actually they are limiting the bandwidth ?.

I want to implement a bandwidth limiting in my FTP code.

Any study or example code about this would be much helpful

thanks in advance

FileZilla is open source, you could read the code for understanding the logic.
More so, since you want to implement it.

Have not looked at the code myself, but usually most limiting algorithms are based on some token-bucket schemes.
