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.

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.

21.6 Configuring Bandwidth Management (General)

Click Advanced > Bandwidth MGMT to open the screen as shown next.

Use this screen to enable or disable bandwidth management, and to enable or disable

automatic traffic classification.

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 non-critical “background” traffic such as bulk transfers that are

allowed but that should not affect other applications and users.
