 How to limit network bandwidth on Linux
 ================================================================================
 If you often run multiple networking applications on your Linux desktop, or share bandwidth among multiple computers at home, you will want to have a better control over bandwidth usage.

Or when you sync a big folder over Dropbox, your roommate may complain that video streaming at her computer gets choppy.
