A testing of IQX hypothesis: An example at data link layer in DSL environment
This paper discovers what parameters of data link layer can be tracked to find relation between QoE (Quality of Experience) and QoS (Quality of Service). It also introduces a new paradigm that relates to consideration of parameters of QoS at all layers of OSI (Open System Interconnection) reference model, and their influence on QoE of end users. In order to analyse relation between data link layer parameters and QoE, the paper presents modification of IQX hypothesis (exponential interdependency of quality of experience and quality of service) in consideration with the mentioned parameters and time. As an example IPTV (Internet Protocol Television) scenario is shown.
