Analysis of quality of service in the controller management of software defined networks (SDN)
Abstract
Software-defined networking (SDN) is a transformative technology with the potential to revolutionize
network management by providing fine-grained control over QoS for network traffic. This project aims
to analyze the QoS in controller management of software-defined networks using the Open Daylight
(ODL) controller, Mininet, and Wireshark.
The project involved the creation of a simulated SDN network using Mininet and the management of the
network using the ODL controller. Network traffic was captured and analyzed using Wireshark. The
main objective was to assess the effectiveness of the ODL controller in managing QoS in the SDN net work.
The results obtained demonstrated that the ODL controller effectively managed QoS in the simulated
SDN network. Different types of traffic were prioritized appropriately, resulting in varying levels of QoS.
Furthermore, the performance of the ODL controller remained unaffected even with an increased number
of flows in the network.
Based on these findings, the ODL controller exhibits promising capabilities for QoS management in SDN
networks. However, additional research is required to evaluate its performance in real-world SDN environments.
