Setting the QoS policy can assign received packets a higher/lower priority (based on your
configuration) to pass through this device. You can define some policies which classify received
packets based on source/destination IP, MAC, port and protocol type. This feature is useful when the
WAN link is very busy or congested or when using special applications that need real time services
such as Internet phone, video conference...etc.
