A graduate student from the Department of Computer Engineering at the University of Technology (Zahra Alaa Baqher) has been awarded a Master of Science degree in “Modified Dijkstra Algorithm with load balanced capability for SDN”, on 08 September, 2019 at the conference hall of the Computer Engineering Department.

In her thesis, two senarios of SDN exploited data networks based on several criteria. In the first scenario, various algorithms were implemented like random load balancer (RLB) and round robin balancer (RRLB), and then weighted round robin round robin balancer (WRRLB) was used to to address the little utilization of servers and to increase the throughput ratio.

In the second scenario, a dynamic load balancing based on SDN data center network topology was proposed in adaptive model for TE. Load balancing becomes dynamic as keep the algorithm running for continuous update of the information. Dijkstra’s algorithm was used to implement the load balancing in SDN application layer for optimizing link utilization in the networks, and the floodlight controller using in the control layer.

The network was tested before and after running the load balancing algorithm. The result shows that the load balancing application increased bandwidth and reduced latency of network, in order to achieve a better result and higher performance of the network.This leads to better resources utilization as a result of using SDN.

The discussion committee consisted of four members, Asst. Prof. Dr. Mohammed E. Younis from the Baghdad University, College of Engineering, Computer Engineering Department as Chairman, Asst. Prof. Dr. Ammar A. AbdalKareem from the Al-Nahrain University, Information Engineering College as a member, Dr. Ahmed S. Kareem from the University of Technology – Iraq, Computer Engineering Department as a member, and Asst. Prof. Dr. Mohammed N. Abdullah from the University of Technology – Iraq, Computer Engineering Department as a member and supervisor.
