DESCRIPTION

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.

 

 

Dest Port

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.

 

 

Priority

Select a priority from the drop-down list box.

 

Highest - Typically used for voice.

 

High - Typically used for video.

 

Mid - Typically used for applications that do not fit into another priority. For

 

example, Internet surfing.

 

Low - Typically used for non-critical “background” applications, such as large

 

file transfers and print jobs that should not affect other applications.
