In order to handle the dynamic network, an automation framework can be developed that adds or remove flows respec-tively. All the flows were manually configured and installed to switches via OpenFlow controller making the network again static in nature. The flows must be carefully configured, since a mismatch leads to packets being forwarded to OpenFlow controller that may decide to broadcast packets, and lead to a drastic reduced throughput from 941 Mbps to approx. In an OpenFlow network, the switch fol-lows its flow table to make forwarding decisions and rejects its traditional forwarding table. OpenFlow controller is the heart of the OpenFlow network, and in centralized hierarchy it poses a single point of failure and risk of DoS attacks.

In this thesis, the integration and benefits of OpenFlow protocol in LAN environment have been analyzed. One of the SDN protocols ‘OpenFlow’ is a normal application layer protocol, which is encapsulated inside TCP, IPv4 and Ethernet format. In SDN, for a single change in network, the network configurations are changed only at central or some specific controller(s) rather than touching individual network devices. Software Defined Networking (SDN) is aimed at surpassing the limits of traditional networking infrastructure and making it a dynamic network. The traditional networking infrastructure is still static in nature due to its complexity, vendor dependence and QoS requirements.
