Abstract: In this work, we introduce decentralized Dynamic Bandwidth Allocation (DBA) schemes capable of supporting upstream Quality of Service (QoS) through differentiated class of service (CoS). In contrast to the centralized approach, the proposed QoS aware distributed DBA supports differentiated services through the integration of both scheduling mechanisms (intra-ONU and inter-ONU) at the Optical Network Unit (ONU). This integration of both scheduling can only be supported by a decentralized architecture. We demonstrate, in addition to the added flexibility and reliability, that the distributed approach has characteristics that make it far better suited than its centralized counterpart for provisioning QoS necessary for properly handling voice, video, and data services over a single line.
