Flow-based dynamic load balancing algorithm for the cloud networks using software defined networks

Abstract

In recent days, cloud computing has become an outstanding technique in all areas that provide various computing resources. The specialty of cloud computing is that it provides excellent services in monitoring, communication, software platform, and infrastructure. Basically, cloud network limits its services in a specific location on the particular zone. When the targeted area is near, the specific server completes the request generated from the user. Few servers are busy while some other servers are idle when it comes to the services. In this case, the provided resources are not used efficiently. To overcome this problem, this paper proposes a concept known as flow-based dynamic load balancing algorithm in cloud networking with software defined networks (SDN). The fundamental principle of this proposed algorithm is distributing client requests equally to all the available servers in a specific cloud network. The main aim of the load balancing algorithm is to optimise the resource utilisation by increasing the throughput, reduce flow completion time, decrease the response time and eliminate the overloading of any individual resource. SDN is mainly used in applying various software functionalities into hardware devices such as routers, switches, etc.
