Software-Defined Networking Controller with Enhanced Traffic Management

SDNs decouple control from data layers enabling simplified management and innovation in networking. These project describe the Network Management System(NMS) which can be implemented by the SDN concept, and in this we use Ryu controller as brain of our NMS. The Ryu controller decouples the control plane (decision-making) from the data plane (data forwarding), which allows for better traffic management capabilities. This approach provides performance and scalability due to the way SDN works, because in large networks we run into challenges such as flexibility, reliability, availability as well as changes in terms of security property which these days plays a critical role. The separation of the control and data planes makes it inherent to realize centralized, flexible, programmable control over network behavior entails new possibilities as well as challenges that the traditional SDN model, its architecture and challenges discussed in this study. The project shows the performance benefits of SDN vs traditional network management approaches by exploring what is possible using the capabilities of the Ryu controller and provides insight into network scalability, flexibility and security.
