NBG6503 User’s Guide

Use this screen to view the amount of network bandwidth that applications running in the network 
are using.

The bandwidth is measured in kilobits per second (kbps). 

The monitor shows what kinds of applications are running in the network, the maximum kbps that 
each application can use, as well as the percentage of bandwidth it is using. 

Figure 99   Management > Bandwidth Management > Monitor

The following is a description of some services that you can select and to which you can apply

FTP

File Transfer Program enables fast transfer of files, including large files that may not be 
possible by e-mail.

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. 

E-Mail

Electronic mail consists of messages sent through a computer network to specific groups or 
individuals. Here are some default ports for e-mail: 

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.
