Abstract
In the past few years, network requirements have been changing frequently as the amount of data traffic increasing exponentially so it is difficult to utilize the full capacity of network resources. Software Defined Networking (SDN) is emerging as a new networking technology which decouples the control plane from the data plane in the network devices. Separation of control and data plane allows a network administrator a better control over network management and also enables new development through network programmability. Presently Open-Flow is the most popular SDN protocol which provides communication between network devices and controller. In this paper, the Round Robin algorithm is compared with the Dynamic load balancing algorithm using the OpenFlow protocol in SDN under varying load conditions of TCP and UDP traffic. Experimental analysis shows that the dynamic load balancing strategy works better than the Round Robin load balancing.
Highlights
In Conventional network architecture, the network devices are vertically integrated means the hardware and software is manufacturer specific which can’t be customized [1] new software or policies may not be installed because of incompatible hardware, or the currently available software couldn’t leverage all the hardware capabilities

Summary
In Conventional network architecture, the network devices are vertically integrated means the hardware and software is manufacturer specific which can’t be customized [1] new software or policies may not be installed because of incompatible hardware, or the currently available software couldn’t leverage all the hardware capabilities. Today’s network devices communicate with each other and are not able to select a path from a global view. These issues are some of the challenges that have motivated the researchers to move forward with some new ideas in networking. The basic idea behind SDN is the decoupling of the data plane from the control plane. The centralized control plane called the controller will control data planes and can be implemented completely in software. This architecture provides a global view of a network the controller is able to see the status of all routes and switches for quickly deciding the best route.
