To address the aforementioned issue, the adaptive least load ratio algorithm wasproposed and followed a straightforward procedure to generate the best possible decisions based onsignificant motivation characteristics identified in dynamic load balancing schemes like LeastConnection-Based and Least Bandwidth-Based. the study was carried out using the HTTPerf tool as itprovided a flexible facility for the generation of various HTTP workloads to evaluate server performance.Results revealed that, while Software defined network was under the influence of client requests loadranging from 0 up to 180 (req/sec), the proposed algorithm confirmed a faster server reply time up to13.37%, server connection time up to 16.3% and average network throughput was improved up to 8%.Moreover, server CPU utilization time and average queue length were reduced to 2.5% and 14%.respectively. accordingly, and based on what the proposed algorithm has achieved in terms ofquantitative performance parameters, it could be adopted in SDN-based data centers.
