Chapter 17 Bandwidth MGMT

17.1.2 Proportional Bandwidth Allocation

Bandwidth management allows you to define how much bandwidth each class gets; however, the actual bandwidth allotted to each class decreases or increases in proportion to actual available bandwidth.

17.1.3 Application-based Bandwidth Management

You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E- mail and Video for example).

17.1.4 Subnet-based Bandwidth Management

You can create bandwidth classes based on subnets. The following figure shows LAN subnets. You could configure one bandwidth class for subnet A and another for subnet B.

Figure 122 Subnet-based Bandwidth Management Example

17.1.5 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.

17.1.6 Scheduler

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