[Abstract] In this paper, we propose software-defined optical access networks architecture, which can improve resource use in an optical access network. This architecture enables flexible service access and highly efficient scheduling. With this technology, we can make the network with centralized control, resource virtualization and business services. In this way, network construction costs can be reduced, and user terminal experience can be improved. This also promotes simple, intelligent next-generation optical access networks.
