CHAPTER 4

Bandwidth Management Wizard

This chapter shows you how to configure basic bandwidth management using the wizard screens.

4.1 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.

4.2 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.

Table 19 Media Bandwidth Management Setup: Services

SERVICE	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 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	The purpose of the TELNET Protocol is to provide a fairly general, bi-directional,
	eight-bit byte oriented communications facility.
	It is typically used to provide user oriented command line login sessions between
	hosts on the Internet. Telnet uses port number 23.
NetMeeting	H.323 is an umbrella recommendation from the ITU-T, that defines the protocols to
(H.323)	provide audio-visual communication sessions on any packet network.
