Autonomic Quality of Experience Management of Software-Defined Networks
Résumé
Quality of Experience (QoE) refers to the subjective evaluation of
the user's perceptions and expectancies during the use of a service. In order
to understand it regarding a given service and how to instrumentally stimulate
it, one must know and model the different factors and parameters related with
technological and human agents. As important as that, is to conceive tools for
managing QoE centered in the user, which adopting a top-down approach, are
able to adapt the resources in the subjacent network infrastructure according to
the user's experience. This study presents an Autonomic Semantic Engine for
QoE Management in Software-Defined Network (SDN) architecture. The Engine
management cycle together with the SDN control application contribute to
the management of QoE with fine granularity, since it minimizes manual settings
and allows the MAPE-K control loops to detect QoE violations and make
decisions for providing the service according to the user's experience.
