Service > QoS (Quality of Service)
QoS (Quality of Service) refers to a network's ability to achieve maximum bandwidth and allow
minimum bandwidth. It guarantees the minimum and limit the maximum bandwidth for certain
class of traffic. The QoS configuration has three parts, including ISP bandwidth, QoS and Status.
ISP bandwidth allows user to configure the max bandwidth for upstream and downstream of
specific WAN interface. Upstream means from LAN to WAN. Downstream means WAN to LAN.
QoS configuration allows user to classify the traffic. Once classified, the traffic will have the
guarantee minimum and limit maximum bandwidth.
Status allows user to monitor the dynamic bandwidth usage.
13.9.1 ISP Bandwidth
User can assign the Upstream and Downstream Bandwidth for each interface. The Bandwidth
unit is kilobits per second.
To prevent guaranteed traffic loss, the assigned bandwidth is better not to exceed the real
bandwidth because the allowable traffic quantity may exceed the real bandwidth.
