Abstract

In the increasing demand of bandwidth hungry applications and services, Passive Optical Network (PON) is consideration of as solitary of the majority optimistic fiber based access system which will offer a cost effective way out to meet the mushrooming development of high bandwidth applications. To endow with first-rate network access to the consumers of a PON system have to utilize a competent bandwidth distribution algorithm, which allot the accessible bandwidth dynamically to the users based on their requirement. This paper proposes a framework and details of a scheduling method based on Dynamic Bandwidth Allocation which meets the Quality of Service (QoS) requirements for differentiated data services in PON networks. The performance of an Optical Line Terminal and Optical Network Units (ONU) can be analysed which explains the QoS of a PON network. For achieving higher bandwidth usage, the proposed method discards leftover unutilized slots through dynamic queue threshold method. This results in accurate bandwidth allocation to each ONU. Simulation results show that the proposed method achieves a better quality aware network for performing an ONU Scheduling.
