Abstract
Quality of Service (QoS) and Quality of Experience (QoE) are two different approaches that evaluate the quality level of a given service. In general, QoS models analyze objective network parameters, while QoE techniques focus on what the user actually perceives when consuming the service (subjective perspective). In this chapter, it is presented a comparative study of two voice codecs employed by two well-known VoIP applications, namely Skype and Jitsi, analyzing the provided quality from two perspectives: objective and subjective evaluations. To this end, several network metrics have been taken into account; in addition, the participants in this study completed different quality surveys in order to obtain their opinion about the evaluated services. Concretely, 60 quality tests with 60 subjects have been performed in a controlled wired scenario. The obtained results suggest a clear relationship between QoS and QoE. This chapter aims to present a detailed description about the process to perform comparative quality evaluations of multimedia services from both QoS and QoE perspectives.
