How do I integrate MPLS and ATM QoS ?
MPLS makes it possible to apply QoS across very large routed or switched networks because Service Providers can designate sets of labels that have special meanings, such as service class. Traditional ATM and Frame Relay networks implement CoS with point-to-point virtual circuits, but this is not scalable for IP networks. Placing traffic flows at the edge into service classes enables providers to engineer and manage classes throughout the network.
