additional applications that you specify.
High priority/Medium priority/Low priority
. For each application, select
High priority
(traffic on this queue
shares 60% of the total bandwidth),

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.
SMTP
(Simple Mail Transfer Protocol). The standard e-mail protocol on the Internet. It is a TCP/IP protocol that
defines the message format and the message transfer agent (MTA), which stores and forwards the mail.
POP3
(Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message store
that holds incoming e-mail until users log on and download it. POP3 is a simple system with little selectivity. All
pending messages and attachments are downloaded at the same time. POP3 uses the SMTP messaging protocol.
Specific Port#
. You can add three additional applications by entering their respective port numbers in the
Specific Port#
fields.
