Chapter III: Advanced Functions
3-1 Quality of Service (QoS)
Quality of service provides an efficient way for computers on the network to
share the internet bandwidth with a preset connection 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 to a specific user.
This tool is very useful for bandwidth
management for the network administrator.
3-1-1 Basic QoS Settings
Please follow the following instructions to set QoS parameters:
Please click ‘Applications and Gaming’ and then click ‘QoS’ tab at the top of

alphanumerical characters)
Bandwidth (b):
Set the bandwidth limitation of this QoS rule. You have
to select the data direction of this rule (Upload of
Download), and the speed of bandwidth limitation in
Kbps, then select the type of QoS: ‘guarantee’
(guaranteed usable bandwidth for this rule) or ‘max’ (set
the maximum bandwidth for the application allowed by
this rule).
Local IP
Specify the local (source) IP address
Address (c):
that will be affected by this rule. Please input the
