MEQA 3 - a multi-end QoS application adaptation architecture

We present MEQA3 application adaptation architecture. MEQA3 manages QoS in two different points of the service activity, 1) the setup/initialisation period and 2) the service period. During the initialisation phase, the system performs an overall optimal QoS to application allocation considering the user requests, the estimated service requirements and the resource constraints. However, during the service time a resource overloading may occur either by bad initial estimation of application requirements or by some unexpected event that limits its performance. Thus, MEQA3 monitors the QoS of the applications on the user's side and if this exceeds the user specifications then dynamically adapts applications to the current situation. We demonstrate by a videoconference example that MEQA3 is an easy to implement low complexity architecture.
