As network component is increasing, the managing and controlling systems from a central based control system becomes very complex. The technology used to resolve this is called Software Defined Networks (SDN) which helps to manage and control the system through programs. SDN stands
as a developing technique that divides single network as data and control plane. The benefit of SDN are provides more performance, managing the packet flow through diverse dealer’s organization components. The complexities continued to raise when implementing network services both from
technical and organizational views. Here in this paper generally focuses on how organizations can deal with the challenge of introducing service chaining and developing critical network services by using the technology SDN and also delivering diverse services of network to user in one system
thus customers can fulfill their desire of services based on requests. The “Service Function Chaining” facility of SDN provides services like Load Balancing, Video Optimizing and Firewall.
