QOS

Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve demanding, real- time applications, such as Internet phone calls or videoconferencing.

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 or low priority for the five preset applications and three additional applications that you specify.

Enable/Disable. To use application-based QoS, select Enable. Otherwise, keep the default, Disable.

High priority/Medium priority/Low priority. For each application, select High priority (traffic on this queue shares 60% of the total bandwidth), Medium priority (traffic on this queue shares 18% of the total bandwidth), or Low priority (traffic on this queue shares 1% 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.

Advanced QoS

This setting allows you to specify traffic queue priority.

Fragment packet’s size of AF and BE traffic to be equal to the size of EF traffic. Select this option to fragmentize the packet sizes for AF (Assured Forwarding) and BE (Best Effort) queues so that it will increase the efficiency for transporting EF (expedited forwarding) queues. Enter a range between 68~1492 bytes.
