Abstract :
Many papers, which submitted as of yet, describe the method of upstream DBA in EPONs. In this paper, we propose the method to improve bandwidth utilization by using modified DRR (deficit round robin) mechanism in ONU scheduling. The ONU provides three different users with their own different upstream bandwidth. In simulation, prime user, medium user, best-effort user, each has been allocated 7500 byte(equivalent to 30 Mbps), 5000 byte (20 Mbps) and 2500 byte (10 Mbps) per one cycle (2 ms). Simulation results show that the proposed method gives more of 10% utilization improvement compared to legacy method
