Abstract

We propose a generalised testing framework to evaluate the end-user perceptual quality of video over IP solutions in enterprise networks. The framework automates testing of communications applications to produce Quality-of-Experience (QoE) results in terms of industry defined standard metrics like PSNR, SSIM and video MOS. Furthermore, it aids in network planning by relating performance indices to network characteristics. Experiments are carried out in an emulated network environment to realise and test the application under varied network impairments. We describe a sample realization of framework using a suite of open source tools and application client extensions. We present a comparative analysis involving performance of two different popular enterprise VVoIP applications which explains the usage of framework as a quality verification and analysis tool. We also present a brief accuracy analysis of Opinion Model using Video Quality Metric (VQM).
