英文摘要： In the process of radio over fiber system, the amount and kinds of transport devices and supporting services have been expanded more and more. The limited scale extension as well as the resources utilization’s inefficiencies is forming a crucial challenge which we have to be faced with. All of those described above force the transition of current radio over fiber from “closed system” to “open networking” and from “rigid configuration” to “elastic control”. This project focuses on the forefront of radio over fiber networking and control technologies with regards to the national strategic development requirements, puts forward an innovative solution which is so-called Software Defined Network based Smart Radio over Fiber Networking (S-ROFN for short) to against those key science problems about the competition game of service complexity and limited spectrum, and low complex multidimensional resource optimization with multiple constraints. Networking model and control mechanism of S-ROFN are mainly researched and three difficult key points will be overcome, which are software defined service processing, resource scheduling, and transport equipment. In order to soften and publish the network control architecture and further the state of current network elements to be reconfigurable and controlled via programming, we will concentrate on comprehensive combination of the process of microwave photonic modules scheduling and service-oriented cognition, and lightwave and microwave resources optimization dynamic networking with system analysis, network organization modeling and protocol emulation, etc. Then achieve the best coupling of dynamic service requirement and open resource control method and provide the theories basis for the development of S-ROFN.
