Various Component handling services for Software Defined Networking (SDN)

Software Defined Networking (SDN) provides us the platform for the easy management of various components, which was not possible in traditional networks. SDN is flexible and scalable because of the separation between control and data plane. OpenFlow protocol acts as the interface between both planes. The concept is that we can create control logic and implement it in network elements of the data plane through centralized control. The controller and the policy need to be updated regularly to meet the requirement of the network. In this paper we have discussed the need of security approaches that can detect any kind of fault or abnormal behavior with in the network and to manage the packet flow metrics. Also how can we distribute the global policy across each of the element in data plane so that the global policy becomes local to each networking elements
