Research On Sdn Application Framework Based On Software Defined Price

The concept of Software Defined Network (SDN) was first proposed by clean slate research group in Stanford University. SDN is a new type of network architecture and technology, the core idea is to separate the control plane and data plane, and programming directly on the control layer to realize the flexible control of network traffic. The main purpose of SDN is to promote innovation in the network business. Through the north interface, developers of SDN can use the software programming approach to call different network resources and ability. Therefore, on the basis of the SDN application, this paper puts forward the concept of Software Defined Price for the first time, and proposes the SDN application framework based on it, then carries on thorough research to the frame work.Firstly, this paper introduces the domestic and overseas research situation of SDN technology, and emphasizes the research status of the SDN application. Secondly, introduce the technology in the implementation of SDN application framework based on Software Defined Price--Maven and REST. Thirdly, this paper introduces the history of programming technologies development, including the desktop application programming, conventional network programming and SDN application programming model. Through the comparison on these programming technologies, the advantage of SDN application programming has been brought out. Then, after analyzing the current service defects of resource pricing and combining with the system of SDN application programming and Software Defined Price, this article puts forward the concept of Software Defined Price and the SDN application framework. Finally, this paper has designed general Software Defined Price module of SDN application framework based on Software Defined Price, including the general pricing module, the general negotiation module and the general trading sub module. Combining with these modules and the virtual tenant network system in OpenDaylight, design and implement the virtual tenant network system based on Software Defined Price. The system design mainly includes the overall design, REST interface design and internal interface. On the basis of design part, this research completes the implementation and test the virtual tenant network system software based on the Software Defined Price.
