8.7. Quality of Service (QoS)
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. All the applications not specified by you are classified as rule
“Others”. The rule with a smaller priority number has a higher priority; the rule with a larger
priority number has a lower priority. You can adjust the priority of the rules by moving them
up or down.
Port-based Qos
This is hardware port-based QoS control method. It will limit the packets throughput in
LAN1~4, WAN port.
Enable Port-based QoS: Check this to enable port-based QoS functionality for the
LAN/WAN port. You can also uncheck to disable.
Priority: High or Low priority level of the transmit packets.
Ingress Rate: The throughput limit of receiving packets.
Egress Rate: The throughput limit of sending packets.
Application-based Qos
This is the application based QoS control method. You can reserve or limit the
bandwidth of some LAN IP address and port number. They will guarantee the throughput
in WAN connection.
Priority Queue Type:
This can put the packets of specific protocols in High/Low Queue. The packets in
High Queue will process first.
