Service

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.
