The Design of a Quality of Experience Model for Providing High Quality Multimedia Services

Abstract. In the last decade, networks have evolved from simple data packet forwarding to platforms that support complex multimedia services, such as net-work-based personal video recording and broadcast TV. Each of these services has significant quality demands: they are very sensitive to packet loss and jitter, and require a substantial amount of bandwidth. As the quality perceived by the end user gives the most accurate view on the streamed service quality, operators are increasing their focus on this type of metric, commonly described as Quality of Experience. This paper presents the design of a Quality of Experience infor-mation model that defines important metrics for measuring service quality. Based on these metrics, we define a novel control loop that represents the rela-tionships among Quality of Experience, the Customer, and network services
