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.
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 Port Priority
Application Port 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.
FTP (File Transfer Protocol). A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For example, after
developing the HTML pages for a website on a local machine, they are typically uploaded to the web server using FTP.
HTTP (HyperText Transport Protocol). The communications protocol used to connect to servers on the World Wide Web. Its
primary function is to establish a connection with a web server and transmit HTML pages to the client web browser.
Telnet. A terminal emulation protocol commonly used on Internet and TCP/IP-based networks. It allows a user at a terminal or
computer to log onto a remote device and run a program.
