Study of Traffic Based Load Balancing Algorithm in the SDN

Software-defined Networking (SDN) has aroused interest in the process of incorporating technology and operating according to the specifications of the consumer for both academia and business and has started to be adopted in the practical use of the platform. the advent of SDN provided another idea of enhancing the system's focal programmability. The load balancing issue needs to be addressed efficiently to manage the incoming traffic and resources and to boost network capacity due to the growing demand and shortage of resources. One of the most important issues is the controller's role in managing the load for better service quality (QoS) at SDN. Load balancing is the technique used in a computer network to split the amount of work between two or more machines working in such a way that the work can be done within the same period. To achieve load balancing, the use of hardware, software, or a combination of both. This paper explores the different types of load balancing algorithms that can help in an SDN environment to efficiently manage resources and provide linear service across multiple customers.
