Review On Architecture & Security Issues of SDN
Software Defined Networking (SDN) is an emerging networking technology which separates the control-logic of data-flow from networking devices. SDN programmatically modifies the functionality and behaviour of network devices using single high level program. It separates control plane and data plane, also provides centralized control. SDN provides several benefits including, network and service customizability, improved operations and better performance. But there are some security issues that need to be taken care of. This paper describes the emergence of SDN as an important new networking technology. The main focus is to explore Security issues related to SDN. Also, the paper reviews and evaluates the salient features of SDN.
