Chapter 19 Bandwidth Management
19.6.2 Maximize Bandwidth Usage Example
Here is an example of a ZyXEL Device that has maximize bandwidth usage enabled on an
interface. The following table shows each bandwidth class’s bandwidth budget. The classes
are set up based on subnets. The interface is set to 10240 kbps. Each subnet is allocated 2048
kbps. The unbudgeted 2048 kbps allows traffic not defined in any of the bandwidth filters to
go out when you do not select the maximize bandwidth option.
The ZyXEL Device divides up the unbudgeted 2048 kbps among the classes that require more
bandwidth. If the administration department only uses 1024 kbps of the budgeted 2048 kbps,
the ZyXEL Device also divides the remaining 1024 kbps among the classes that require more
bandwidth. Therefore, the ZyXEL Device divides a total of 3072 kbps of unbudgeted and
unused bandwidth among the classes that require more bandwidth.
19.6.2.1 Priority-based Allotment of Unused and Unbudgeted Bandwidth
The following table shows the priorities of the bandwidth classes and the amount of bandwidth
that each class gets.
Suppose that all of the classes except for the administration class need more bandwidth.
• Each class gets up to its budgeted bandwidth. The administration class only uses 1024
kbps of its budgeted 2048 kbps.
• The sales and marketing are first to get extra bandwidth because they have the highest
priority (6). If they each require 1536 kbps or more of extra bandwidth, the ZyXEL
Device divides the total 3072 kbps total of unbudgeted and unused bandwidth equally
between the sales and marketing departments (1536 kbps extra to each for a total of 3584
kbps for each) because they both have the highest priority level.
