| Abstract |
Software-Defined Networking (SDN) is a data network paradigm that defines the separation of the data plane and control plane so that applications can change network behavior through software algorithms. Many academic solutions are focused on network performance reduction. However, these works lack experimental evaluation in a physical environment. Many of these proposed solutions were evaluated in simulated/emulated environments, so these solutions are not suitable for production cases. The present research determined the influence of a proposed Networking Monitoring System (NMS) in a real SDN environment. Relevant results and an exhaustive statistical test were done to evaluate the influence of NMS on the physical server performance in a real SDN environment. The average CPU usage with ONOS is 1.47%, but the average CPU usage with ONOS + NMS is higher at 1.84%. Memory usage average with ONOS is 18.81 GB, but the average memory usage with ONOS + NMS is higher at 19.24 GB. The focus of NMS is on being a platform that permits future networking specialists to learn and research in a real SDN environment. Future networking researchers are encouraged to use production controllers such as ONOS, which works with OF-DPA and Pica8 switches. |
