require guaranteed bandwidth (like video streaming and network telephone) will be affected,
therefore an unpleasing result will occur, like the interruption of video / audio transfer.

With this function, you can limit the maximum bandwidth or give a guaranteed bandwidth for a
specific computer, to avoid said unpleasing result from happening.
