18-4 Media Bandwidth Management
The following figure shows the bandwidth usage with the maximize bandwidth usage option enabled. The
Prestige divides up the unbudgeted 64 Kbps among the rules that require more bandwidth. If the
administration department only uses 32 Kbps of the budgeted 64 Kbps, the Prestige also divides the
remaining 32 Kbps among the rules that require more bandwidth. Therefore, the Prestige divides a total of 96
Kbps total of unbudgeted and unused bandwidth among the rules that require more bandwidth.
In this case, suppose that all of the rules except for the administration rule need more bandwidth.
Each rule gets up to its budgeted bandwidth. The administration rule only uses 32 Kbps of its
budgeted 64 Kbps.
Sales and Marketing are first to get extra bandwidth because they have the highest priority. If they
each require 48 Kbps or more of extra bandwidth, the Prestige divides the total 96 Kbps total of
unbudgeted and unused bandwidth equally between the sales and marketing departments (48 Kbps
extra to each for a total of 112 Kbps for each) because they both have the highest priority level.
R&D requires more bandwidth but only gets its budgeted 64 Kbps because all of the unbudgeted
and unused bandwidth goes to the higher priority sales and marketing rules.
The Prestige does not send any traffic that is not defined in the bandwidth filters because all of the
unbudgeted bandwidth goes to the rules that need it.

The following is a table describing the priorities that you can apply to traffic that the Prestige forwards out
through an interface.
