چکیده مقاله:
Software defined networking (SDN) is an emerging networking paradigm which gained a lot of interests from both academia and industry. SDN decomposes the control plane from the data plane and allows for the network logic to run on a software-based controller. This decomposition of network operations offers the simplification of network management and greater ease of configuration through network programmability. In this paper, we first comprehensively discuss the state-of-the-art experiences in this field and their existing challenges. We also categorize the challenges facing SDN and its integration with other technologies such as network function virtualization (NFV), internet of thing (IoT), 5G networks, big data, and optical networks. Then, considering the key issues, we revisit the SDN architecture and propose a comprehensive conceptual framework and some detailed architectural considerations for enhancing the capabilities of SDN networks. The proposed conceptual framework also applies IoT controllers and hypervisors to support IoT applications and virtualized networks respectively. Moreover, we present future research works according to the proposed framework.
