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

16.1 Bandwidth Management Overview

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).

16.2 Application-based Bandwidth Management

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

16.3 Subnet-based Bandwidth Management

You can create bandwidth classes based on subnets.
