Abstract
<p class="0abstract">Software-Defined Networking (SDN) is the developing technology and has the advantages of handling dynamic nodes in the network with improved performance. SDN has the problem of allocating the resources to the user with high latency and this affects the overall system performance. To solve this problem, the routing method based on Bellman Ford Algorithm (BFA) is proposed in the SDN. The Bellman-Ford has less computation time in identifying the shortest path in the nodes of SDN graph. The BFA is applied to identify the optimal path for the nodes to the user with low latency. The BFA is compared with Dijikstra’s algorithm to analyze its performance. The experimental outcome shows that the BFA has lower latency compared to the Dijkstra's algorithm. The lower computation time is achieved due to BFA has a lower magnitude time in vertices and edges compared Dijkstra's algorithm. The Dijkstra’s algorithm has the latency of 10.8 ms, while proposed BFA has the latency of 2.97ms.</p>
