Leveraging SDN-based management for improved traffic scheduling in PONs

Building on top of an Software-Defined Networking (SDN)-based management architecture developed in previous works, we add advanced traffic scheduling, QoS and energy saving features to Time- and Wavelength Division Passive Optical Networks (TWDPONs). We are able to manage some parameters of the Dynamic Bandwidth Algorithm (DBA), including the scheduling policy and weight-based QoS differentiation of users, taking into account the laser tuning time, an important and realistic constraint in multiwavelength PONs that is usually neglected.
