IP QoS
The DSL device provides a control mechanism that can provide different priority to different users or data
flows. The QoS is enforced by the QoS rules in the QoS table. QoS rule contains two configuration blocks:
Traffic Classification
and
Action
. The
Traffic Classification
enables you to classify packets on the basis of
various fields in the packet and perhaps the physical ingress port. The
Action
enables you to assign the
strictly priority level for and mark some fields in the packet that matches the Traffic Classification rule. You
can configure any or all field as needed in these two QoS blocks for a QoS rule.
