英文摘要： The Software Defined Open Optical Access Network (SDOOAN) concept extends the benefits of Software Defined Networking into broadband access, and makes dumb access pipes become flexible, open and smart, which is an important developing direction for broadband access networks in the Internet era. Theoretical model, architecture and control mechanism are key problems for SDOOAN that need to be solved in the present. This project mainly focus on the following aspects: (1) Theoretical model and resource abstract method for SDOOAN; (2) Enable technologies for SDOOAN, including architecture, northbound/southbound control interface, dynamic network virtualization and application oriented network programming technology; (3) Software defined solutions for SDOOAN to enable smart pipes. On the basis of the SDOOAN concept, establish an innovative experimental system to verify our proposals..Based on these innovative scientific studies and experimental works, we expect to make breakthroughs for SDOOAN in the follows aspects: Hierarchical control architecture, dynamic control and resource mapping mechanism for virtualized access networks, network programming technology and smart pipe solutions, and experimental systems. The research results provide a steady base in theory and technology for the realization of a flexible, open and smart optical access network, and effectively support the development of broadband networks in the Internet era.
