This paper proposes an innovative, flexible, and easily repro- ducible test bed that facilitates large scale multimedia (MM) quality centric experiments. It makes use of Linux container technologies and several other utilities that collectively facili- tate ease of deployment, minimal resource utilisation and better reproducibility. We outline the significant advantages of this ap- proach over physical test beds, virtual machines and simulation and showcase it in an experiment dealing with speech quality aspects of WebRTC using the state-of-the-art quality prediction model, i.e. POLQA. However, it can be easily extended for any type of real time communication (RTC) and MM content. The particular test bed involves a single host on which multiple We- bRTC based VoIP endpoints run within Linux containers. The test bed also comprises a native network emulator running be- tween the endpoints. Several other tools are additionally incor- porated in the test bed so that speech quality of the transmitted signal can be evaluated using objective quality prediction mod- els, such as PESQ, POLQA, etc.
