Integrated Rate and Credit Feedback Control for ABR Service in ATM Networks
We propose a ow-control scheme that combines the merits of credit- and rate-based ow-control schemes by applying direct control over both bandwidth and bu er resources. The goal of the proposed scheme is to design an optimal ratecontrol policy for a given nite bu er capacity that maximizes average throughput and bounds end-to-end delay. By applying higher-order rate control, the proposed scheme not only makes the rate process converge to the neighborhood of link bandwidth, but also con nes the queue-length uctuation to a regime bounded by bu er capacity (thus guaranteeing lossless transmission). Using the uid approximation method, we model the proposed ow-control scheme and study the system dynamic behavior for ABR (Available Bit Rate) service under the most stressful trac condition. We derive the expressions for queue build-ups and average throughput in both transient and equilibrium states. The analytical results have shown the proposed scheme to be stable and ecient in that...
