    The wide growth in the technology and connectivity is influencing a hyper-connected world of a large number of devices connected and communicating with each other. The networks are aimed to build from a large number of network devices such as routers, switches and various types of middleboxes. It means that the devices with many complex protocols executed on them which control the traffic for other purposes than packet forwarding, for instance, a firewall. Network operators majorly deal with the designing the approaches to deal with a wide range of network events and applications. However for the changing of network conditions they accomplish is the manual transformation of these high level-strategies into low-level configuration commands. Generally, they require a very limited access to the tools to complete these very difficult tasks.


      As a result, the variation of network management and performance is comparatively challenging and thus error-prone. The reason behind this is that the network devices are in general vertically-integrated black boxes worsens the challenge for the network operators and administrators face.

At present, the wireless technologies, for example, 3G/4G are developing IP connectivity which aims to provide faster internet connection, along with the multimedia application and a multitude of services with improved performance, easy deployment, and low-cost implications. Conversely, the services request and traffic patterns variety are growing very fast.


Considering the fast development in the connection of network and connected devices, existing installed 3G/4G wireless network does not meet the demand for high performance which is expected in 5G wireless networks. 5G principally run a user main connectivity where numerous applications are gain access to a faster speed, at higher capacity and at 1ms potential. The 5G is an important tool for comprehending Internet of Thing (IoT) model connecting a large number of devices as it is proficient of supportive machine-to-machine (M2M) communication at low cost and low battery consumption assuring high quality of services (QoS).


The 5G wireless systems require re-engineering in the design of existing communication and network technologies in implementation and deployment. For this reason, the flexibility and cost efficiency for the controlling of a large number of connected devices is not possible with current 3G/4G architecture. Furthermore, the present scale is not enough to accomplish the estimated gain and performance necessities in M2M communication, and industrial automation as estimated from 5G mobile systems in term of IoT. That’s why 5G is exploring both in the academia and in the industry empowering technologies to be parameterized. These empowering technologies include Software Defined Networks (SDNs) and Network Function Virtualization (NFV).







The SDN (Software Defining Network) is a new networking standard that has arisen with new chances for network enthusiasts to experiment and establish progressive ways of network management and to actively take control of packet forwarding in their network. It gives the expectation to change the limitations of current network infrastructures. SDN basically redefine the network architecture by splitting the control plane from data plane and this provides sustenance for mixed network interaction with fast development by using programmable planes. Whereas NFV is responsible for freedom from the fundamental complexity and resource allocation for multiple users effortlessly connected to the network.


An open issue in the cellular network is the complication of 5G and cellular network protocol and implementation involve abstraction. For that reason, a unlike existing structural design for a cellular network in the framework of SDN is planned that the SDN founded cellular architecture can redesign the cellular communication in IP connectivity.
