摘要：

Building on top of a Software-Defined Networking (SDN)-based management architecture developed in previous works, we are working on adding traffic scheduling, QoS and energy saving features to Time- and Wavelength-Division Passive Optical Networks (TWDM PONs). We present a brief summary of our SDN-based architecture and some results obtained with a Dynamic Bandwidth Allocation (DBA) algorithm based on IPACT. We are able to manage some parameters such as weight-based QoS differentiation of users, taking into account the laser tuning time, an important and realistic constraint in multi-wavelength PONs that is usually neglected in research papers.
