Active Service Quality Management in ASEMA system

Abstract

One of the purposes of the Active Service Environment Management system (ASEMA) is to provide the best possible multimedia service experience to end users. This is realized by dynamically adapting to changes in service environment¿s configuration and used network infrastructure¿s quality of service (QoS) changes. The research problem of the paper is to find a solution for proactive approach to manage multimedia service performance in a dynamic service environment. The research is based on the constructive method by analyzing the related publications and experimentation with the selected technologies by implementing the solutions part of the ASEMA prototype. The prototype has profile negotiation functionality that dynamically updates ASEMA profiles according to dynamic changes in an end user¿s service environment. The quality of service management functionality in ASEMA monitor¿s actively underlying network¿s QoS level. It adjusts quality of video stream according to the changes in QoS levels of the used network infrastructure.
