25.6 Application and Subnet-based Bandwidth Management

You could also create bandwidth classes based on a combination of a subnet and an
application. The following example table shows bandwidth allocations for application specific
traffic from separate LAN subnets.

25.7 Scheduler

The scheduler divides up an interface's bandwidth among the bandwidth classes. The
ZyWALL has two types of scheduler: fairness-based and priority-based.

25.7.1 Priority-based Scheduler

With the priority-based scheduler, the ZyWALL forwards traffic from bandwidth classes
according to the priorities that you assign to the bandwidth classes. The larger a bandwidth
class's priority number is, the higher the priority. Assign real-time applications (like those
using audio or video) a higher priority number to provide smoother operation.

25.7.2 Fairness-based Scheduler

The ZyWALL divides bandwidth equally among bandwidth classes when using the fairness-
based scheduler; thus preventing one bandwidth class from using all of the interface's
bandwidth.

25.7.3 Maximize Bandwidth Usage

The maximize bandwidth usage option (see
divide up any available bandwidth on the interface (including unallocated bandwidth and any
allocated bandwidth that a class is not using) among the bandwidth classes that require more
bandwidth.
