At the provider edge of a core network, an egress interface may schedule based on a class dominance model, a destination dominance model or a herein-proposed class-destination dominance model. In the latter, queues are organized into sub-divisions, where each of the subdivisions includes a subset of the queues having a per hop behavior in common and at least one of the subsets of the queues is further organized into a group of queues storing protocol data units having a common destination. Scheduling may then be performed on a destination basis first, then a per hop behavior basis. Thus providing user-awareness to a normally user-unaware class dominance scheduling model.
