QoS Support

Introduction of QoS

Quality of Service (QoS) refers to both a network's ability to deliver data with
minimum delay, and to the networking methods used to control the use of
bandwidth. QoS allows the ZyXEL device to group and prioritize application
traffic and fine-tune network performance.

Without QoS, all traffic data is equally likely to be dropped when the network is
congested. This can cause a reduction in network performance and make the
network unfit for time critical applications such as video-on-demand.
1. Click Network Setting > QoS > General; if you want to modify the QoS
configuration you need to disable this feature first.
2. Click on "Queue Setup".
3. You can "Add new Queue" or "Edit" the Queues displayed in the
screenshot. The Priority and Weight can be adjusted.
