The QoS Tab - Application-based QoS
Quality of Service (QoS) ensures better service to high-priority service.
Application-based QoS involves Internet traffic, which may involve demanding, real-time applications, such as
videoconferencing. To enable Application-based QoS, you can select either Priority Queue or Bandwidth
Allocation.
Priority Queue. Application-based QoS manages information as it is transmitted from LAN to WAN. Depending on
the settings of the Priority Queue, this feature will assign infromation a high or low priority for the five preset
applications and three additional applications that you specify. For each application, select High Priority or Low
Priority. The packets will be put into High or Low Priority Queue for the egress port of WAN according to your
settings. Specific Port #. You can add three additional applications by entering their respective application port
numbers in the Specific Port # field.
Bandwidth Allocation. For each of the three Application Level Gateways (ALGs), you can choose a Bandwidth
Allocation Policy from Guaranteed and Spare with a specified percentage value to control the bandwidth
utilization from LAN to WAN. It depends on specified policy to let the bandwidth to be reserved or shared with the
applications. Guaranteed wil reserve specific bandwidth for the applications and Spare will use the remaining
bandwidth for other applications.
User Define Button. You can define the policies regarding source or destination IP, protocol and port number. You
also can mark the DSCP field with specific value to egress packets. The bandwidth utiliazation could be
controlled from LAN to WAN.
When you have finished making changes to the screen, click the Save Settings button to save the changes, or
