Flow Optimization in Multipath Network using Maximum Flow Algorithm to Improve the Bandwidth Usage in SDN

Traditional network architecture is distributed and complicated compared to the Software Defined Networking (SDN) that modifies the distributed network architecture to a centralized one and makes the management of the network easy. The problem arises in the network flow of the multipath network and finding the maximum flow among the source node and destination node. But, the present network situation in the data centers which uses the multipath topology needs a maximization in the flow to improve the bandwidth usage. This research presents to find the maximum flows and avoiding augmented paths (where we can call this finding the path barrier) in the multipath network and forwarding the network traffic flow from source to the destination. In this project, a Dinic's max flow algorithm is used to find the maximum flows and maximize the bandwidth usage in the software defined network. The Mininet network emulator and RYU controller is used in the implementation. The outcome from the investigation of this research removes network congestion and complications which improves the network bandwidth usage
