24.6 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.

TRAFFIC TYPE

The scheduler divides up an interface's bandwidth among the bandwidth classes. The

ZyWALL has two types of scheduler: fairness-based and priority-based.

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.

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

The maximize bandwidth usage option allows the ZyWALL to 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.
