En naturlig sammanband mellan användarupplevt tjänstekvalitet och störningar på nätverksnivå (Swedish)
Extended abstract with formulae. Excerpts as follows: During the recent years, networked applications and services on top of Internet such as e-business, voice communication and media distribution and have become popular. This development has entailed a growth of interest in end-user-perceived Quality of Service (QoS). The recently proposed Quality of Experience (QoE) concept includes both end-to-end network-level Quality of Service (QoS) and user satisfaction with the service. Besides of factors such as network coverage, service offers and level of support, even subjective factors such as user experience and perception need to be taken into account. A major challenge, however, consists in quantifying losses of QoE from the users’ points of view. As far as network problems are the reason for perceived quality problems, it is worthwhile to have formulae at hand that reflect the impact of perturbations on user perception. They might be used to quantify depreciations of user perception based on comparably simple-to-measure network-level parameters. In this contribution, we propose an exponential relation between user perception and perturbations on network level, which looks like a natural law.
