Note the same four queues are used for all traffic coming from the DSL line.

Strict priority is used in the scheduling of the overload protection.

2. PVC policing

Discards frames if the traffic from the End-user on that PVC exceeds the

configured bandwidth. This policing discards frames randomly. This policing

is optional and is configured per service.

3. VLAN mapping

Maps the frames to VLANs. The mapping is done on basis of the PVC from

which the frame came from, or the PVC and Ethertype (IP or PPPoE) – if

there are two services with two VLANs defined with that same PVC.

4. Classification

Sets the p-bit for the frame. The classification is based on one of the

following:

• PVC

• PVC and Differentiated Services Code Point (DSCP) value (comes from

the End-user)

• PVC and Ethertype

The method and the values of the conversion are defined when the service

is created.

5. CoS flow policing

Discards frames if the outgoing traffic for that CoS flow exceeds the

specified bandwidth. This policing is optional, and is configured per service.
