An SDN Approach: Quality of Service using Big Switch’s Floodlight Open-source Controller

Quality of Service in today’s packet-switched networks have various effecting factors that include both technical and non-technical aspects. Such factors include the reliability of service, availability of service, delay, scalability, effectiveness, grade of service etc. These factors play an important role into how a particular network may treat and handle packets within a given network. Properties of packet-switched networks can cause low throughput, dropped packets, corruption errors, latency, jitter, disordered delivery and more. The role of SDN allows for network operating systems to gain greater governance of the control plane within a given network. Using this SDN approach and the specifications provided by OpenFlow (OF) 1.0[1] we show an approach to Quality of Service that is managed and defined by a centralized network controller.
