An OpenFlow Based Multipath Transmission Mechanism
Ming Hu, Hui Liu Bo Xing, Changyou Xu Bo · 2016
In order to solve the traffic engineering problems such as low throughput and poor load balancing in high connected data center networks, an OpenFlow based Multipath Transmission (OFMT) mechanism is proposed. By taking advantage of OpenFlow centralized control, OFMT calculates precisely the transmission path for each flow and assigns optimally the traffic flow in all transmission paths, it also executes periodic polling and dynamic scheduling mechanisms to achieve good load balancing and high throughput. The experimental results show that the network throughput is significantly improved in OFMT compared with typical data center transport protocols, and OFMT shortens the flow completion time under the same traffic workloads.
