14.4  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.
14.5  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. 
14.5.1  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.
