Bandwidth Management
22.1  Overview 
This chapter contains information about configuring bandwidth management and editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an 
application. 
In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth 
management is applied before sending the packets out to the WAN. Downlink traffic comes back 
from the WAN device (B)  to the LAN device (A). Bandwidth management is applied before sending 
the traffic out to LAN.

Bandwidth Management Example
You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual 
applications (like VoIP, Web, FTP, and E-mail for example).
22.2  What You Can Do
• Use  the  General screen (
) to enable bandwidth management and 
assign bandwidth values.
• Use  the  Advanced screen (
) to configure bandwidth managements rule 
for the pre-defined services and applications.
• Use  the  Monitor screen (
) to view the amount of network bandwidth 
that applications running in the network are using.
