Deploying QoS (Quality of Service) management to guarantee that all applications receive
the service levels required and sufficient bandwidth to meet performance expectations is
indeed one important aspect of modern enterprise network.
One reason for QoS is that numerous TCP-based applications tend to continually increase
their transmission rate and consume all available bandwidth, which is called TCP slow start.
If other applications are not protected by QoS, it will detract much from their performance in

Define the default speed of the upstream for each computer in
LAN.
Define the default speed of the downstream for each computer
in LAN.
Router will detect if there is enough bandwidth remained for
using according to the bandwidth limit set by the user. If yes,
the router will adjust the available bandwidth for users to
enhance the total utilization.
Display a list of specific limitations that you set on this web
page.
Bandwidth limit can be applied on certain IP range. That's,
only the PCs within the range will be influenced by the
bandwidth limitation set here. Please define the start IP
address for the specific limitation.
Define the end IP address for the specific limitation.
Click the radio button to determine the specific limitation will
be applied to.
Each – The bandwidth limit for transmission and receiving
(TX limit and RX limit) will be applied to each PC on certain
IP range.
Shared - The bandwidth limit for transmission and receiving
(TX limit and RX limit) will be shared by all of the PCs on
certain IP range.
Define the limitation for the speed of the upstream to be
applied as specific limitation. If you do not set the limit in this
field, the system will use the default speed for the specific
limitation you set for each index.
Define the limitation for the speed of the downstream to be
applied as specific limitation. If you do not set the limit in this
field, the system will use the default speed for the specific
limitation you set for each index.
Add the specific speed limitation onto the list above.
Allows you to edit the settings for the selected limitation.
Remove the selected settings existing on the limitation list.
You can type in four sets of time schedule for your request.
All the schedules can be set previously in Application –
Schedule web page and you can use the number that you have
set in that web page.
