Design And Implementation Of SDN Service Platform

Especially in recent years, with the continuous development of the Internet, with the rise of social networks, cloud computing, the network layer is faced with large amount of data and complex structure, the situation in a wide range of business. The traditional network architecture has become more and more bloated, reform of the architecture of the network layer is imperative. SDN (software defined network) pointed out the direction for the reform of network architecture. As Openflow technology matures, urgently needs a SDN based business platform to implement based on Openflow related business and achieve business management, in order to better explore the SDN technology.This paper based on Openflow technology and Web development technology, realization of SDN business platform building. Complete Query Module, the Flow Management Module. And on this basis, realize the Switch Configuration Based on Time Period and Network Topology. At the same time to achieve a better user experience, user can be intuitive to Openflow network management.This paper first introduces the relevant background and development status of SDN, points out the necessity of building SDN business platform based on Openflow protocol. Further introduces the related theory and technology of SDN business platform, including Openflow network, the LAMP architecture, data format of Json, etc. Then carries on the overall design of the system, including the design of the system architecture, each function module and the business requirement analysis, and determined the cross-domain problem solution, on this basis, complete the construction of the overall system structure and each module design and implementation of the business, including the Query Module, Flow table Management Module design and implementation, Switch Configuration Based on Time Period as well as the working process of the Network Topology service, implementation process and the front display. Solve the problem of interaction between the business platform and the bottom controller, and the network topology is made up of the business with drag and drop functionality. Finally, design the test environment, validate the function of each module and the business one by one, and through the test results verify the accuracy of SDN related business.
