软件定义光网络资源获取与分配方案设计

With the development of network technology, to achieve separation of control and forwarding, software control of the network software-defined networking (SDN) become a hot spot, and the research focus has developed from a data network to the optical network, optical network research called Software defined optical network, in SDON, the structure and function of the optical network based on user or operator needs, the use of software programming approach to dynamic customization, enabling rapid response to requests, the efficient use of resources, flexible service purposes. Based on OpenFlow on its expansion, we designed a set of optical network resource acquisition and allocation of the program.
