Figure 34 Bandwidth Management Wizard: General Information

VoIP (SIP) 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.

SIP is transported primarily over UDP but can also be transported over TCP, using

the default port number 5060.

Telnet 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 TCP port 23.

TFTP Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP, but

uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control

Protocol).

WWW 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.
