3.3.5 QoS

Quality of service, QoS provides an efficient way for computers on the network to share the

internet bandwidth with a promised quality of internet service. Without QoS, all computers and

devices on the network will compete with each other to get Internet bandwidth, and some

applications which 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.
