Research of Dynamic Bandwidth Allocation Scheme of GPON

Zhao Xiao-jing

Abstract

This paper proposes a new dynamic bandwidth allocation(DBA)scheme-two level DBA scheme based on QoS,and shows the flowchart of this algorithm,concerning the study of GPON on its key technique in the MAC layer:Dynamic Bandwidth Allocation(DBA).The performance analysis and comparison proves that the new algorithm can improve net throughput,which will realize the fairness for both different ONUs and services.
