Quality of Experience (QoE) and Network Performance Modelling for Multimedia Traffic
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. |
