Abstract
Modern network traffic is dynamic, requiring robust and efficient load balancing to maintain performance and reduce congestion. This paper implements the Least Bandwidth Utilization Ratio (LBUR) algorithm in ONOS Intent Path Forwarding (IPF) to dynamically balance network demand across available paths. LBUR prioritizes traffic forwarding channels with the lowest bandwidth usage in Software-Defined Networks (SDN) to increase bandwidth utilization and reduce delay. The algorithm^s performance was tested using the Abilene network topology under various traffic situations. LBUR lowers congestion, balances load, and minimizes end-to-end latency compared to classical load balancing. These data suggest LBUR could improve SDN network efficiency and reliability.
