3.3.26 Qos(Quality of Service)
The QoS can let you classify Internet application traffic by source/destination IP address and port number. You can
assign priority for each type of application and reserve bandwidth for it. The packets of applications with higher priority
will always go first. Lower priority applications will get bandwidth after higher priority applications get enough
bandwidth. This can let you have a better experience in using critical real time services like Internet phone, video
conference etc. You can adjust the priority of the rules by moving them up or down.
Note: If the total assigned bandwidth of higher priority applications is larger than the maximum bandwidth provided by
the WAN port, the other applications will not get any bandwidth.
