Bandwidth Management Wizard

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

6.1 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.

6.2 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.
