In future Internet, multi-network services correspond to a new paradigm
that intelligence in network control is gradually moved to the edge of
the network. As a consequence, the application itself can influence or
determine the amount of consumed bandwidth. Thus the user behaviour may
change dramatically. This impacts the Quality of Service (QoS) and the
Quality of Experience (QoE), a subjective measure from the user
perspective of the overall value of the provided service or
application. A selfish user or application tries to maximize its own
QoE rather than to optimize the network QoS, in contrast to a legacy
altruistic user.
In this paper we present the IQX hypothesis which assumes an
exponential functional relationship between QoE and QoS. This
contribution is a first step towards the quantification of the QoE for
edge-based applications, where an example of VoIP is taken into
account. Starting from a measurement of the Skype application, we show
the basic properties of selfish and altruistic user behaviour in
accordance to edge-based intelligence. The QoE is quantified in terms
of MOS in dependence of the packet loss of the end-to-end connection,
whereby Skype's iLBC voice codec is used exemplarily. It is shown that
the IQX hypothesis is verified in this application scenario.
Furthermore, selfish user behaviour with replicated sending of voice
datagrams is investigated with respect to the obtained QoE of a single
user. In addition, the impact of this user behaviour on congestion in
the network is outlined by means of simulations.
