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 and VoIP.
1. Click Network Setting > QoS > General, and activate the QoS service,
then set the Maximum Upstream bandwidth value to 509 to fully
utilize WAN bandwidth.
