16.7.5 Maximize Bandwidth Usage Example

Here is an example of a Prestige 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.

Table 50 Maximize Bandwidth Usage Example

BANDWIDTH CLASSES AND ALLOTMENTS
Root Class: 10240 kbps
The Prestige 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 Prestige also divides the remaining 1024 kbps among the classes that require more
bandwidth. Therefore, the Prestige divides a total of 3072 kbps of unbudgeted and unused
bandwidth among the classes that require more bandwidth.

16.7.5.1 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 51 Priority-based Allotment of Unused and Unbudgeted Bandwidth Example

BANDWIDTH CLASSES, PRIORITIES AND ALLOTMENTS
Root Class: 10240 kbps
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 Prestige
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.
