The Applications & Gaming Tab - QoS
Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve
demanding, real-time applications, such as videoconferencing on IP phones.
There are three types of QoS available, Device Priority, Application Priority, and Ethernet Port Priority.
• Enabled/Disabled. To limit outgoing bandwidth for the QoS policies in use, select Enable. Otherwise, select
Disable.
• Upstream Bandwidth. Select the bandwidth to be used from the drop-down menu.This setting allows you to
limit the outgoing bandwidth for the QoS policies in use, so you can control how much bandwidth a particular
application is allowed to use.
Device Priority
Enter the name of your network device in the Device name field, enter its MAC Address, then select its priority
from the drop-down menu.
Ethernet Port Priority
Ethernet Port Priority QoS allows you to prioritize performance for four of the Router’s ports, LAN Ports 1-4. For
each of these ports, select High or Low for Priority. For Flow Control, if you want the Router to control the
transmission of data between network devices, select Enable. To disable this feature, select Disable. The
Router’s other four ports will be automatically assigned low priority. Incoming Rate Limit limits the incoming
bandwidth. To use this feature, select 8M, 4M, 2M, 1M, 512K, 256K, or 128K (M stands for Mbps, while K
stands for kbps). If you do not want to use this feature, keep the default, Disable.
Ethernet Port Priority QoS does not require support from your ISP because the prioritized ports are LAN ports
going out to your network.
Application Priority
Application Priority QoS manages information as it is transmitted and received. Depending on the settings of the
QoS screen, this feature will assign information a high or low priority for the five preset applications and three
additional applications that you specify. For each application, select High or Low for Priority. For Specific Port#,
you can add three additional applications by entering their respective port numbers in the Specific Port# fields.
