Dual-Band Wireless A+G Broadband Router The Applications and Gaming Tab - QoS QoS (Quality of Service) manages information as it is transmitted and received. It ensures better service to highpriority types of Internet traffic, which may involve demanding, real-time applications, such as videoconferencing. QoS can also prioritize traffic for a specific device or the Router's LAN ports. Qos (Quality of Service) There are three types of QoS available, Application Port Priority, MAC Address Priority, and LAN Port Priority. Application Port Priority Depending on the settings of the QoS screen, this feature will assign information a specific priority for up to five preset applications and up to five additional applications that you specify. Application Name. Each drop-down menu offers a choice of ten preset applications (select None if you do not want to use any of the preset applications). Select up to five preset applications. For custom applications, enter the name of your application in one of the available fields. The preset applications are among the most widely used Internet applications. They include the following: 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. 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. DNS (Domain Name System). The way that Internet domain names are located and translated into IP addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address. TFTP (Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password capability. Finger. A UNIX command widely used on the Internet to find out information about a particular user, such as a telephone number, whether the user is currently logged on, and the last time the user was logged on. The person being "fingered" must have placed his or her profile on the system in order for the information to be available. Fingering requires entering the full user@domain address.
