An approach to improve scalability and quality of services in software define networking.

Abstract

Software Defined Networking (SDN) is platform that support network application more efficiently. SDN is successful because it decoupled the control plane from its data plane. Detachment of these two-planes improved dynamic configuration, controller programmability, centralized and decentralized network. In this study, Distributed SDN approach is used to avoid scalability and robustness issue. The SDN controller logically centralized but it works on multiple nodes that physically distributed. Distributed nodes communicate with each other and improve the network performance to assist data flow. When flow arrives through end devices to any data plane in Distributed SDN, our approach will support the data plane to increase controller response time. In addition, controller will check, whether data needs to prioritize flow to send locally or globally with the help of Elephant or Mice flow. Proposed approach used to reduce the controller work load, response time and manage Quality of Services (QoS) between controllers
