Chapter 19 Bandwidth Management
257
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.
19.6.2.2
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 ZyXEL Device 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.
19.6.3
Bandwidth Management Priorities
Traffic with a higher priority gets through faster while traffic with a lower priority is dropped
if the network is congested. The following table describes the priorities that you can apply to
traffic that the ZyXEL Device forwards out through an interface.

DESCRIPTION
High
Typically used for voice traffic or video that is especially sensitive to jitter (jitter is the
variations in delay).
Mid
Typically used for “excellent effort” or better than best effort and would include important
business traffic that can tolerate some delay.
Low
This is typically used for non-critical “background” traffic such as bulk transfers that are
allowed but that should not affect other applications and users.
