An Adaptive Routing Scheme for Heterogeneous Data-Flows Using Openflow

In this paper, we propose an open flow controller that takes into account different application's needs such as latency, bandwidth, reliability, network jitter, etc and optimizes the flow on a combination of such factors. It is a dynamic system that constantly keeps track of these parameters and adapts to changes happening in the network and pushes updated rules on the fly to the switches. Such a system can efficiently route traffic in data-center by routing packets from different applications in separate routes as per requirement, thereby utilizing the resources more judiciously. We built a prototype controller using POX and studied its routing characteristics extensively. We used network-bandwidth, latency and reliability as the parameters to test the system and simulated the network using mininet and found that the system was able to balance these three parameters for different loads according to the requirements.
