Towards the investigation of TCP fairness in software defined networking

Abstract

Software Defined Networking (SDN) is the latest technology that is appealing to academics, industry, and researchers. Through this technology, many software applications can be controlled in a big way, such as reinstalling the route, monitoring hardware devices with software and connecting with Internet, etc. Efforts are being made to deal with SDN-based network issues such as node deployment architecture, localization, network protocols, operating systems, virtualization, and power problems, despite repeated improvements to solve it. We have used the TCP subflow to measure the viability of the connection in the virtual environment. The main work is to distribute data between subflows and control the network connections. Each TCP subflow is sending to the network, and we have also monitored network assets throughout the broadcast in the Ether Network. TCP rates are as per the proportion of modified rates and verify the TCP Fairness. Establishment of connectivity in the SDN controller and SDN devices is also part of our experiment, and the acknowledgment policy is also used. OpenFlow protocol is used to validate messages passed through SDN devices or controllers, and to store information as an open flow table. After that, we check the improved access performance in the simulated testbed and compare the existing algorithm.
