Bandwidth Management
21.1  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.
Figure 105   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).
21.2  What You Can Do
• Use  the  General screen (
) to enable bandwidth 
management and assign bandwidth values.
