Feasibility study and implementation of openflow based SDN controller for tactical scenario

Over the past few years in traditional networks, issues such as lack of orchestration, agility, flexibility, increased demand for scalability, and vendor dependence are of major concern. An innovative concept of Software Defined Networking(SDN) is a possible solution to all these problems which aims at increasing network efficiency and simplifying network management. It includes a physical separation of the control plane and data plane in a network device. The intelligence and control of the network operation such as routing is removed from the network devices and is concentrated in a centralized component called the SDN Controller [10]. This paper demonstrates the implementation of OpenFlow based SDN controller in C language on Visual Studio-IDE. Communication between the switch and controller is captured using Wireshark. Nodes connected to the switch are able to exchange strings, files etc. The current networking issues and their solution in tactical scenarios are discussed using different use cases.
