Table 59 Media Bandwidth Management Setup: Services SERVICE FTP WWW Telnet E-Mail DESCRIPTION File Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail. FTP uses port number 21. The World Wide Web (WWW) 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. WWW uses port 80. Telnet is the login and terminal emulation protocol common on the Internet and in UNIX environments. It operates over TCP/IP networks. Its primary function is to allow users to log into remote host systems. Telnet uses port 23. 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 VoIP (SIP) SMTP - port 25 Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. BitTorrent Gaming SIP is transported primarily over UDP but can also be transported over TCP, using the default port number 5060. BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software and media files using ports 6881 to 6889. BitTorrent requires you to search for a file with a searching engine yourself. It distributes files by corporation and trading, that is, the client downloads the file in small pieces and share the pieces with other peers to get other half of the file. Online gaming services lets you play multiplayer games on the Internet via broadband technology. One example is Microsoft's Xbox Live, which uses port 3074. As of this writing, your NBG-417N supports Xbox, Playstation, Battlenet and MSN Game Zone. 15.5.4 Services and Port Numbers See Appendix E on page 235 for commonly used services and port numbers. 134 NBG-417N User's Guide
