Bandwidth Management Wizard
This chapter shows you how to configure basic bandwidth management using the wizard
screens.
5.1
Introduction
Bandwidth management allows you to control the amount of bandwidth going out through the
ZyXEL Device’s WAN port and prioritize the distribution of the bandwidth according to
service bandwidth requirements. This helps keep one service from using all of the available
bandwidth and shutting out other users.
5.2
Predefined Media Bandwidth Management Services
The following is a description of the services that you can select and to which you can apply
media bandwidth management using the wizard screens.

DESCRIPTION
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.
FTP
File Transfer Program enables fast transfer of files, including large files that may
not be possible by e-mail. FTP uses TCP (Transmission Control Protocol) port
number 21.
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:
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
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.

NetMeeting
(H.323)
A multimedia communications product from Microsoft that enables groups to
teleconference and videoconference over the Internet. NetMeeting supports VoIP,
text chat sessions, a whiteboard, and file transfers and application sharing.
NetMeeting uses H.323. H.323 is a standard teleconferencing protocol suite that
provides audio, data and video conferencing. It allows for real-time point-to-point
and multipoint communication between client computers over a packet-based
network that does not provide a guaranteed quality of service.
H.323 is transported primarily over TCP, using the default port number 1720.
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.
VoIP (H.323)
Sending voice signals over the Internet is called Voice over IP or VoIP.
H.323 is a standard teleconferencing protocol suite that provides audio, data and
video conferencing. It allows for real-time point-to-point and multipoint
communication between client computers over a packet-based network that does
not provide a guaranteed quality of service.
H.323 is transported primarily over TCP, using the default port number 1720.
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).
