Description
		As the network has limited resources, the traditional network with a single path routing mechanism will make the inefficient network resource utilization. Because the competitive utilization along the single path causes the performance degradation of traffic flows. Multipath routing is a good approach for inefficient resource utilization problem. It distributes the traffic load among parallel paths instead of single path. Moreover, the long flows which called elephant flows are needed to detect and handle in order to avoid traffic congestion. This paper proposes an effective solution by combining the elephant flow detection and rerouting based on end-to-end delays of available paths in Software Defined Network (SDN). The proposed method is implemented by using ONOS controller and Mininet emulator. The experimental results prove that 16.57%~78.03% throughput improvement and 26.18%~171.68% flow completion time (FCT) reduction for multiple elephant flows compared with the single path routing approach.
