Real Time Quality of Service Pathfinder

This work is based on using the Software Defined Networking (SDN) concept to design and develop algorithms and mechanisms to achieve end-to-end Quality of Service (QoS) for real-time applications. The algorithm (Pathfinder) is responsible for the dynamic and on demand provisioning of network resources upon changes in the application traffic requirements. To this target, we make use of the standardized OpenFlow protocol which allows the separation of the control and data planes and supports basic ways to offer QoS. The solution builds up an SDN Application (SDNApp) based on the Network as a Service paradigm (Naas) to provide Real Time QoS over an Openflow-based network, adapting the control plane to satisfy the requirements of an application or service.
