Software Defined Networking (SDN), now categorized as network efficient technology because it can support the dynamic nature of the functions of the networks and it is making operating cost lower, because of simplify the hardware and software. It is also simplify the management. Unfortunate well understanding for the computer science students about SDN concepts in general is still weak regards to the overlapping concepts of networks in general. This paper gives general light about SDN from different angels like what is SDN, why SDN, architecture, framework, models, application, opportunities, trends, benefits and challenges this paper aims to illustrate and give good theoretical conception about the SDN.
