Chapter 20 Bandwidth Management
20.8.1 Reserving Bandwidth for Non-Bandwidth Class Traffic
Do the following three steps to configure the ZyWALL to allow bandwidth for traffic that is
not defined in a bandwidth filter.
1
Leave some of the interface’s bandwidth unbudgeted.
2
Do not enable the interface’s
Maximize Bandwidth Usage
option.
3
Do not enable bandwidth borrowing on the sub-classes that have the root class as their
parent (see
20.8.2 Maximize Bandwidth Usage Example
Here is an example of a ZyWALL 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 ZyWALL 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 ZyWALL also divides the remaining 1024 kbps among the classes that require more
bandwidth. Therefore, the ZyWALL divides a total of 3072 kbps of unbudgeted and unused
bandwidth among the classes that require more bandwidth.
20.8.2.1 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.
Table 110
Maximize Bandwidth Usage Example
BANDWIDTH CLASSES AND ALLOTMENTS
Root Class: 10240 kbps
Administration: 2048 kbps
Sales: 2048 kbps
Marketing: 2048 kbps
Research: 2048 kbps
