Service

The following is a description of the applications you can prioritize with WMM 

QoS. Select a service from the drop-down list box. 
•

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
•

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.
•

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 services are user specific services configured using known ports 

and applications.
