Abstract

Software defined networking (SDN) promises a paradigm shift in real-time traffic management by offering centralized network control and programmability. The present work leverages SDN technology for dynamic resource allocation in campus environments with a view to improve Voice over Internet Protocol (VoIP) communication between end-systems. To correctly record user perceived voice quality the mathematical E-Model and Mean Opinion Score (MOS) mapping is used. Using administrator defined minimum MOS threshold for VoIP calls, the SDN control plane is used to compute real-time network load, and dynamically allocate network resources between calling agents. During validation, the proposed design is tested over a six hundred node simulated campus SDN environment. The quantitative and qualitative QoE results for the present approach, depict an MOS improvement of between 17-33% over conventional route selection and traffic management schemes. Furthermore, the relative consistency in improved MOS values, translating for constantly high call quality motivate further adoption of the present design in practical campus SDN setting.
