Fast GATE Mechanism with Prediction-based DBA for Differentiated Services on EPONs

Abstract

This study proposes a novel Fast GATE Dynamic Bandwidth Allocation (FGDBA) mechanism incorporated with a prediction-based scheme in Ethernet passive optical networks (EPONs). Two phase dynamic bandwidth allocation mechanisms are designed in the proposed FGDBA which also followed by the prediction scheme and fairness bandwidth allocation. The FGDBA mechanism can eliminate idle period problem in traditional DBA mechanism and improve overall PON system performance. The simulation results show that the proposed FGDBA mechanism with prediction-based DBA is able to provide excellent performance as compared with other well-known methodologies.
