TRACKING AND MANAGING QOE IN THE INTERNET : TOWARDS COOPERATIVE QOE MANAGEMENT SCHEMES

With many different players involved in the end-to-end service delivery chain, identifying the root causes of QoE impairments and finding effective solutions for meeting the end users’ requirements and expectations in terms of service quality has become a challenging task. The majority of QoE-based management approaches to-date may be primarily related to either network management or application management, hence different QoE optimization and control loops are involved and interact (e.g., dynamic application adaptation, network resource management). A research question we aim to address is to what extent cooperative management schemes and underlying business models involving multiple players can achieve efficient management of network/system resources, while enhancing customer QoE. Furthermore, it is necessary to identify solutions for the coordination and information exchange among actors involved in the service delivery chain in order to provide channels for effective QoE control/improvement. This white paper provides an overview of research interests within the NetMedia research group (FER, Univ. of Zagreb) as related to topics in the context of tracking and managing QoE in the Internet.
