Abstract
Generic relationships between QoE and QoS have been
intensively discussed in literature for single QoS
parameters and often found to be logarithmic or
exponential. While there are many experimental studies
investigating statistically the influence of several
parameters on QoE, the generic relationship be-tween
them, and how to best model it, have not been discussed
so far. For communication networks, however, there is a
major interest from different stakeholders to have
multi-dimensional QoE models. The contribution of this
paper is an analysis of the generic relationship between
QoS and QoE for multiple QoS parameters and its
implications. We address the question of
whether multi-dimensional QoE models for several
parameters are additive or multiplicative. In an
analytic model and with examples involving HTTP
non-adaptive video streaming, we show that a
multiplicative model has different properties than the
current additive QoE model proposed in ITU-T standards.
We want to raise sensitivity in the community on
multi-factor QoE models, their properties, and the need
for multi-factor stud-ies to confirm the appropriate
models.
