Journal ArticleDOI
Network survivability modeling
TL;DR: The assessment of the survivability of a network with virtual connections exposed to link or node failures is addressed and results show very good correspondence between the transient loss and delay performance in simulations and in the analytic approximations.
Journal ArticleDOI
Modeling of Aggregated IoT Traffic and Its Application to an IoT Cloud
TL;DR: The main goal of this paper is to understand the level of accuracy of the Poisson approximation model and derive guidelines as to when a Poisson process can be assumed for aggregated periodic IoT traffic.
Journal ArticleDOI
QoE beyond the MOS: an in-depth look at QoE via better metrics and their relation to MOS
TL;DR: The limitations of MOS are put forward, other statistical tools that provide a much more comprehensive view of how quality is perceived by the users are presented, and the results of several subjective studies with these tools are analyzed.
Journal ArticleDOI
Definition of QoE Fairness in Shared Systems
TL;DR: It is argued that neither QoS fairness nor Jain’s fairness index meet all of the desirable QoE-relevant Properties, which are met by the proposed inline-formula, so the proposed index may be used to compareQoE fairness across systems and applications, thus serving as a benchmark for QOE management mechanisms and system optimization.
Journal ArticleDOI
Dependability of the NFV Orchestrator: State of the Art and Research Challenges
TL;DR: This paper provides necessary background information, reviews the available literature, outlines the proposed solutions, and identifies some design and research problems that must be addressed.
