16.2 The QoS General Screen

Use this screen to enable or disable QoS and have the ZyXEL Device automatically
assign priority to traffic according to the IEEE 802.1p priority level, IP precedence
and/or packet length.
Click Advanced > QoS to open the screen as shown next.

DESCRIPTION
Select the check box to turn on QoS to improve your network
performance.
You can give priority to traffic that the ZyXEL Device forwards out through
the WAN interface. Give high priority to voice and video to make them
run more smoothly. Similarly, give low priority to many large file
downloads so that they do not reduce the quality of other applications.
Enter the amount of bandwidth for the WAN interface that you want to
allocate using QoS.
The recommendation is to set this speed to match the interface's actual
transmission speed. For example, set the WAN interface speed to 1000
kbps if your Internet connection has an upstream transmission speed of 1
Mbps.
You can set this number higher than the interface's actual transmission
speed. This will stop lower priority traffic from being sent if higher priority
traffic uses all of the actual bandwidth.
You can also set this number lower than the interface's actual
transmission speed. This will cause the ZyXEL Device to not use some of
the interface's available bandwidth.
