Quality of Experience (QoE) and Network Performance Modelling for Multimedia Traffic
Journal of Artificial Intelligence and Big Data
| Vol 1, Issue 1
Table 1. Comparison Between QoS and QoE Parameters
| Aspect | Quality of Service (QoS) | Quality of Experience (QoE) |
| Definition | Objective measure of network performance using technical parameters. | Subjective assessment of user satisfaction with the service. |
| Measurement Basis | Network metrics (delay, jitter, packet loss, throughput). | User perception metrics (MOS, SSIM, VMAF, buffering rate). |
| Layer of Evaluation | Network layer and transport layer. | Application layer and user layer. |
| Primary Focus | Ensuring network reliability and performance. | Ensuring user satisfaction and perceived service quality. |
| Influencing Factors | Network congestion, bandwidth, packet delay variation. | Content quality, playback smoothness, device type, user expectations. |
| Measurement Tools | Network analyzers, SNMP, Wireshark, QoS probes. | Subjective testing, ITU-T standards, QoE estimation models. |
