Abstract—As the increasing number of access devices, and the complex and changeful of access site and the media, energy consumption of power distribution communication access networks is expected to further grow in the future, energy saving has become a key issue with the development of Passive Optical Networks (PONs). In this paper, we propose a Software Defined Distribution Optical Network (SD-DON) architecture, design an energy saving aware control strategy which support unified optimization and efficient scheduling from multi-domain perspective. Additionally, a Multi-Modes Hybrid Dynamic Bandwidth Allocation (MH-DBA) scheme are proposed and evaluated under SD-DON, in which, 4-saving modes and multi-period mixed adaptive dormancy method is designed to maximize energy saving of Optical Network Units (ONUs). Simulation results show that MH-DBA can significantly save energy under different traffic loads, and clearly outperform the conventional scheme.
