Software Defined Networking: A Paradigm Shift in Networking for Future, Emerging Trends and Applications

摘要

Software defined Networking is an emerging topic in area of networking aimed at providing efficient and faster implementation of networking devices to support various applications in current world aimed at dynamic scaling of the network infrastructure to provide minimum time for upgrading as well as testing new protocols. The main aim of SDN lies in the separation of the currently co-existing control plane and data plane. This decentralisation involves providing greater leverage of access and intelligence to the control plane for controlling multiple network devices efficiently with minimum manpower. The control plane is designed such that the interactions with the application layer offer users to more programmatically control and define the network control. This papers aims at providing an insight into the concepts of SDN, the features of the SDN controller, applications of SDN and emerging areas of SDN implementation as well as points to be considered in developing efficient and secured SDN controllers.
