15.1.2 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.
15.1.3 Application-based Bandwidth Management
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).
15.1.4 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 79 Subnet-based Bandwidth Management Example
15.1.5 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.
15.1.6 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.
Table 64 Application and Subnet-based Bandwidth Management Example
TRAFFIC TYPE FROM SUBNET A FROM SUBNET B
VoIP 64 Kbps 64 Kbps
Web 64 Kbps 64 Kbps
FTP 64 Kbps 64 Kbps
E-mail 64 Kbps 64 Kbps
Video 64 Kbps 64 Kbps
