Due to the emergence of the Internet of Things and 5G networks, there’s an
enormous pressure on the underlying communication networks in terms of demand,
performance requirements and dynamic management. To manage incoming traffic, a load
balancing technology is assigned to server clusters. In traditional networks, routing forward
traffic in keeping with the shortest path to reduce cost. This might result in abnormal
distribution of traffic causing overloading of communication links. Recently, Software
Defined Networks (SDNs) has become increasingly popular and a potential candidate to
beat traditional networks limitations. Software Defined Networks (SDNs), described by an
ideal separation of the control and data planes, is being approved as a distinct paradigm for
complex network management. This research analyzes the performance of Weighted
Least Connection, round robin, weighted round robin and least load balancing
algorithms. The analysis focuses on key metrics: response time (seconds), transaction
rate (transactions/second), Lose packet Rate (%) and throughput (MB/second).
Moreover, a new OpenFlow topology based Multi-Controller Topology with three
Controllers is proposed. Compared to a single-controller topology and Multi-Controller
topology with two Controllers utilizing Weighted least Connection, round robin,
weighted round robin and least load balancing algorithms in an SDN POX controller, the
proposed multi-controller topology with four Controllers demonstrates significant
improvements Reduced response time by an average of 28.76%,Increased transaction
rate by an average of 21.73%,Enhanced throughput by an average of 66.58% and
decreased the Lose packet Rate by an average 0.049%
Keywords: Software Defined Networks, Load-balancing Algorithm,
