The paper comprises of several interfaces in between several layers of SDN architecture. There are four interfaces defined eastbound westbound northbound southbound each. Different kinds of methods & techniques, as well as targeted audiences, have been displayed concerning literature review is also defined. The components and its pros cons are well signifying its noted value. The major challenges encountered thereafter a reflected in SDN techniques and report cards through it curb its challenges and benefits discussed thereafter.
The various segment of SDN is defined including its controllers those are centralized structures, distributed structure and multilayer structure. Therefore, we can conclude by abstracting a graph scale through which an audience can easily simplify its implementation thereon.
