英文摘要： The gradual deployment of cloud computing, Internet of things and big data analysis will accelerate communication network architecture and technology innovation.The multi-granularity optical transport architecture and key technologies based on software definition is the latest focus of the transport network. This project aims at facing to future application needs , and key technologies including multi-granularity optical transport network structure, multi-granularity switching network virtual mechanism, multi-granularity management & control scheme, bandwidth variable transmission technology, multi-granularity optical transport network evaluation mechanism will be further investigated. The research will be performed in a combination of theoretical study, numerical simulation and experimental validation. The new structure and the corresponding implementation mechanism of software defined multi-granularity optical transport network are expected to be proposed, based on which the experimental validation and evaluation studies will be carried out. The content and expected results of the project will provide a reference architecture and implementation mechanism for future development of software driven-oriented multi-granularity switching optical communication network, and further effectively enhance the holistic approach and application level of China's software-defined network technology.
