QoS (Quality of Service)
QoS To use QoS, select Enable. Otherwise, keep the
default, Disable.
Application-based QoS
Application-based QoS manages information as it is
transmitted and received. Depending on the settings of
the QoS screen, this feature will assign information a high,
medium, or low priority for the five preset applications
and three additional applications that you specify.
The five preset applications are the following:
FTP (File Transfer Protocol)
A protocol used to transfer files over a TCP/IP network
(Internet, UNIX, etc.). For example, after HTML pages
are developed 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 more applications by
entering their respective port numbers in these fields.
High priority/Medium priority/Low priority For each
application, select High priority (traffic on this queue
shares 70% of the total bandwidth), Medium priority
(traffic on this queue shares 15% of the total bandwidth),
or Low priority (traffic on this queue shares 10% of the
total bandwidth).
