Utilizing SDN to Deliver Maximum TCP Flow for Data Centers

Abstract

Data centers host tens of thousands of interconnected servers, and they need to move a vast amount of data from one server to another for mirroring and backup purposes. Many new network technologies have been used to provide high throughput for bulk transfers of data in data centers. One of the evolving structures is the software-defined network (SDN), which is a new network paradigm that eases network management by separating the control plane from the data plane. In this paper, we introduce a novel method of utilizing traditional TCP and SDN to deliver maximum flow throughput. We also discuss our evaluation of our new method, MaxFlowTCP, against StandardTCP, ParallelTCP, and MPTCP. The results show that MaxFlowTCP provides higher throughput for the tested topology. Compared to StandardTCP, MaxFlowTCP had 130% better throughput, and compared to ParallelTCP and MPTCP, it had an average of 40% more throughput.
