A Comparative Analysis of QoS, GoS, and QoE Metrics in Network Performance Evaluation

The concepts of QoE (quality of experience), QoS (quality of service), and GoS (goal of service) are commonly discussed in network performance and user satisfaction studies. Although QoE has become a popular topic in research, the boundaries between QoS and QoE are often blurred, making it difficult to clearly define them. This paper examines the differences and relationships between these terms with regard to their practical applications. QoS is a subjective metric that reflects how users perceive a service. It is influenced by personal preferences and various environmental factors. GoS measures the probability of a successful connection or call under certain conditions. The results showed that implementing QoS features such as traffic prioritization can positively affect both GoS and QoE by reducing packet loss and improving service reliability. It is shown how network performance management using QoS tools can improve user experience and overall service reliability, providing a clearer understanding of how these concepts interact in practice.
