Chapter 19 Bandwidth Management 202
• 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.
• 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.
19.8.2.2 Fairness-based Allotment of Unused and Unbudgeted Bandwidth
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 Prestige 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
19.9 Bandwidth Borrowing
Bandwidth borrowing allows a sub-class to borrow unused bandwidth from its parent class,
whereas maximize bandwidth usage allows any bandwidth class to borrow any unused or
unbudgeted bandwidth on the whole interface.
Enable bandwidth borrowing on a sub-class to allow the sub-class to use the parent class’s
unused bandwidth. The parent class’s unused bandwidth is given to the highest priority sub-
class first (see Section 19.9.1 on page 203).
The total of the bandwidth allotments for sub-classes cannot exceed the bandwidth allotment
of the parent class. The Prestige uses the scheduler to divide the parent class’s unused
bandwidth among the sub-classes that have bandwidth borrowing enabled.
