Congestion Control Mechanism in Software Defined Networking by Traffic Rerouting

Software defined networking enables the network administrator to have centralized control over the entire network by splitting the data plane from the control plane. Software Defined Network also enables the user to program the various network elements. With increasing amount of traffic in the current day network, congestion tends to be a vital problem to be solved. The congestion in the networks is caused by a heavy surge of packets at one particular region on the topology. The congestion can be avoided using the SDN framework with the shortest path algorithm where several shorter parts of similar lengths are found and the traffic is redirected based on the obtained traffic details. The obtained results show that the throughput and bandwidth values have increased considerably.
