DESCRIPTION
Type a description of the application priority.
The following is a description of the applications you can prioritize with WMM
QoS. Select a service from the drop-down list box.
• E-Mail
Electronic mail consists of messages sent through a computer network to
specific groups or individuals. Here are some default ports for e-mail:
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
• FTP
File Transfer Protocol enables fast transfer of files, including large files that it
may not be possible to send via e-mail. FTP uses port number 21.
• WWW
The World Wide Web is an Internet system to distribute graphical, hyper-
linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/
server protocol for the World Wide Web. The Web is not synonymous with the
Internet; rather, it is just one service on the Internet. Other services on the
Internet include Internet Relay Chat and Newsgroups. The Web is accessed
through use of a browser.
• User-Defined
User-defined services are user specific services configured using known ports
and applications.
This displays the port the selected service uses. Type a port number in the
field provided if you want to use a different port to the default port.
Select a priority from the drop-down list box.
