摘要：Software Defined Networking (SDN) approach which allows the network operator to manage network elements using software running on external server. This is accomplished by a split in the architecture between the forwarding element and the control element. This paper proposes the OpenFlow as a way of networking where the controlling software is moved to one or more hardware module (controllers) which can control many switches. Flow table in all the forwarding elements (Switches) are modified by the centralized controller, and so all the routing information is centralized to controller. OpenFlow provides a standardize interface for remotely controlling the forwarding tables in network switch, routers and access Finally this paper shows the features and the concept of information centralization
