25.7.5.1 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 138
BANDWIDTH CLASSES, PRIORITIES AND ALLOTMENTS
Root Class: 10240 kbps | Administration: Priority 4, 1024 kbps |
|
|
| Sales: Priority 6, 3584 kbps |
|
|
| Marketing: Priority 6, 3584 kbps |
|
|
| Research: Priority 5, 2048 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 ZyWALL 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.
•Research requires more bandwidth but only gets its budgeted 2048 kbps because all of the unbudgeted and unused bandwidth goes to the higher priority sales and marketing classes.

The following table shows 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 ZyWALL divides the total 3072 kbps total of unbudgeted and unused bandwidth equally among the other classes. 1024 kbps extra goes to each so the other classes each get a total of 3072 kbps.
