21.5 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.
Table 132 Application and
TRAFFIC TYPE | FROM SUBNET A | FROM SUBNET B |
VoIP (SIP) | 64 Kbps | 64 Kbps |
|
|
|
Web | 64 Kbps | 64 Kbps |
|
|
|
FTP | 64 Kbps | 64 Kbps |
|

64 Kbps | 64 Kbps | |

21.5.1 Bandwidth Management Priorities
Traffic with a higher priority gets through faster while traffic with a lower priority is dropped if the network is congested. The following table describes the priorities that you can apply to traffic that the ZyXEL Device forwards out through an interface.
Table 133 Bandwidth Management Priorities
PRIORITY | DESCRIPTION |
High | Typically used for voice traffic or video that is especially sensitive to jitter (variations in |
| delay). |
|
|
Mid | Typically used for “excellent effort” or better than best effort and would include important |
| business traffic that can tolerate some delay. |
|
|
Low | This is typically used for |
| allowed but that should not affect other applications and users. |
