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. See Figure 7-22.
QoS
There are two types of QoS available, Application-based and Port-based.
• Enabled/Disabled. To use QoS, select Enabled. If you do not want to use QoS, keep the default, Disabled.
Application-based QoS
Application-based 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 priority or Low priority. If you select
Disable, then QoS will be disabled for that application.
• 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.
