QoS - Quality of Service

QoS helps you to control the data upload traffic of each application from LAN (Ethernet) to WAN

(Internet). It facilitates you the features to control the quality and speed of throughput for each

application when the system is running with full upstream load.

Quality of Service: Check to activate this function and the following field will be available.

If Enable QoS checkbox is selected, choose a default DSCP mark to automatically mark incoming

traffic without reference to a particular classifier.

If Enable Qos checkbox is not selected, all QoS will be disabled for all interfaces.

Select Default DSCP Mark: Select the default DSCP mark from the list-box. Differentiated Services

Code Point (DSCP) is the first 6 bits in the ToS byte. DSCP Mark allows users to classify the traffic

of the application to be executed according to the DSCP value. The default DSCP mark is used to

mark all egress packets that do not match any classification rules.

Note: Before configuring Queue config and QoS Classification section, you must enable QoS

function, for the reason that the queues’ activation will depend on this, the classification will also

depend on this.

The corresponding IP precedence and DSCP mapping table is listed below.
