Bandwidth Management
This chapter contains information about configuring bandwidth management, editing rules and
viewing the ZyXEL Device’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 ZyXEL Device applies bandwidth management to traffic that it forwards out through an
interface. The ZyXEL Device 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 ZyXEL Device
and be managed by bandwidth management.
• The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN)
must be less than or equal to the WAN speed that you configure in the Bandwidth
Management Summary screen.
• The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN) must be
less than or equal to the LAN speed that you configure in the Bandwidth Management
Summary screen.
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.
The following figure shows LAN subnets. You could configure one bandwidth class for
subnet A and another for subnet B.
