A dynamic bandwidth allocation based on transfer rate ratio for efficient ABR service in ATM networks

In this paper, we propose a dynamic bandwidth allocation based on transfer rate ratio to efficiently provide ABR service in ATM networks. The proposed method is a measurement-based approach for a distributed bandwidth allocation of explicit rate. The ATM switch can rapidly adapt to the bandwidth variation of ATM networks and the transfer rate variation of ABR source. The proposed method also makes the best use of the available bandwidth of ATM networks. The simulation results demonstrate that the proposed method achieves the more fair bandwidth allocation and higher link utilization than those achieved by existing methods.
