Quality of Service in packet‑switched networks depends on technical and non‑technical factors—reliability, availability, delay, scalability, effectiveness—that affect packet handling and can lead to low throughput, packet loss, errors, latency, jitter, and disordered delivery. The paper proposes a QoS model managed by a centralized SDN controller using OpenFlow 1.0 specifications. The model defines QoS by programming the controller to enforce service parameters across the network via OpenFlow 1.0.
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.
