NBG334W User’s Guide

This chapter contains information about configuring bandwidth management, editing rules and 
viewing the NBG334W’s bandwidth management logs.

ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based 
on an application and/or subnet. You can allocate specific amounts of bandwidth capacity 
(bandwidth budgets) to different bandwidth rules. 
The NBG334W applies bandwidth management to traffic that it forwards out through an 
interface. The NBG334W does not control the bandwidth of traffic that comes into an 
interface.
Bandwidth management applies to all traffic flowing out of the router, regardless of the 
traffic's source.
Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the NBG334W and 
be managed by bandwidth management. 

• The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, 

WLAN to WAN, WAN to WAN / NBG334W) must be less than or equal to the 
Upstream Bandwidth that you configure in the Bandwidth Management Advanced 
screen. 

• The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WLAN 

to LAN, LAN to LAN / NBG334W) must be less than or equal to 100,000 kbps (you 
cannot configure the bandwidth budget for the LAN port). 

• The sum of the bandwidth allotments that apply to the WLAN port (LAN to WLAN, 

WAN to WLAN, WLAN to WLAN / NBG334W) must be less than or equal to 54,000 
kbps (you cannot configure the bandwidth budget for the WLAN port). 

You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).

You can create bandwidth classes based on subnets.
