The concept of PqoS (end-to-end perceived QoS), although in general it deals with the user satisfaction with a specific delivered/requested service, is in practice significantly differentiated by the nature of each delivered service. This chapter reviews various existing PQoS assessment methods for video, VoIP, on-line games and web services that have been published in the literature. It then moves beyond the current PQoS assessment methods and presents novel techniques for predicting the PQoS of a multimedia service.
