Chapter 4 Bandwidth Management Wizard

70

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

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.

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.
