I. Introduction
The Global Internet Phenomena Report 2021 [2] uncovers that almost 80% of web traffic consists of video, gaming and social media content. Among them, at least 51 % of video streams are transmitted using adaptive bit rate video streaming methods [3]. On an average, every Internet user spends around seven hours per week watching videos on the web and therefore, there is a constant user demand for better video streaming quality. Studies have shown that users rapidly leave video sessions if the quality is not adequate, resulting in income losses for the content suppliers.
