In certain embodiments, a method for bandwidth allocation includes receiving at least a first traffic flow and a second traffic flow, each traffic flow including at least committed information rate (CIR) and excess information rate (EIR) parameters. The CIR parameter in each traffic flow is associated with a corresponding guaranteed pass-through rate. The first traffic flow and the second traffic flow are stored in first and second queues, respectively. The first queue is associated with a first provisioned weight, and the second queue is associated with a second provisioned weight. The method further includes scheduling downstream transmission of the first traffic flow and second traffic flow stored in the first and second queues according to at least first and second implementation weights that are determined based on a bandwidth of a downstream communication link, a CIR parameter of the first queue, a CIR parameter of the second queue, and each of the first and second provisioned weights.
