Chapter 21 Bandwidth Management

The following figure shows LAN subnets. You could configure one bandwidth class for
subnet A and another for subnet B.

21.4 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.

21.5 Scheduler

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

21.5.1 Priority-based Scheduler

With the priority-based scheduler, the ZyXEL Device 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.
