Abstract

In this paper, a distributed Dynamic Bandwidth Allocation (D-DBA) scheduling mechanism for star-ring protection architecture is proposed in Ethernet Passive Optical Networks (EPONs). The D-DBA mechanism can effectively resolve the idle period problem and reduce overload of OLT in traditional DBA mechanism. We perform exhaustive simulation experiments to study the performance and validate the usefulness of the proposed mechanism. The simulation results show that the proposed D-DBA mechanism can reduce the packet delay and packet delay variation for high priority ONUs to ensure Quality of Service (QoS).
