Abstract Increasing popularity of real time applications has imposed the need to ensure quality ofservice for the applications in network Therefore providing quality of service in today snetworks has become an important goal Considering the limitations of distributed controlplane in traditional networks in order to provide a solution to this problem SDNarchitecture has emerged which by separating the control plane from the data plane creatsa flexible platform for the implementationof any desired quality of service algorithm In this thesis a new method in SDN architecture is presented to provide quality of servicefor delay sensitive real time applications In this method the SDN controller monitors thestatus of the existing queues in the output ports of the switches in the network inconsecutive periods of time then based on the collected information in case ofinappropriate conditions in high priority queue some of the flows in this queue aretransferred to lower priority queues By doing this delay for real time flows in the networkcan be controlled The main features of this algorithm that distinguishes it from perviousworks are the way the queue length in SDN switch is measured and the calculation ofdelay of queues using the queue length Simulation results show the effectiveness of theproposed algorithm in guaranteeing required level of delay for delay sensitive applicationsconsidering the capacity of queues on a selected path Keywords SDN QoS OpenFlow
