Dynamic Bandwidth Allocation (DBA) Algorithm for Passive Optical Networks

Abstract

The emergence of Passive Optical Network (PON) technology, which is one of the important solutions for 5G bearer network enables the telecommunications industry to provide users with services with higher transmission rates and lower construction costs, compared with the traditional bandwidth access mode. This paper mainly analyses the dynamic bandwidth allocation (DBA) of the NG-PON, proposes a novel scheme based on traditional DBA algorithm and introduces a DBA algorithm supporting quality of services (QoS) and services hierarchy. This algorithm can divide the services into different priority. The results show that the improved DBA can effectively improve channel utilization and reduce average delay.
