Network Design Implications of QoS and QoE
1 like313 views
The document discusses the implications of Quality of Service (QoS) and Quality of Experience (QoE) in network design, classifying mapping models into black-box, glass-box, and gray-box categories. It covers various parameter-based models for video services and offers insights into actionable QoE solutions and monitoring approaches. Additionally, it highlights QoE-based management strategies for VoIP calls and vertical handover processes.

- 3. 1. CLASSIFICATION OF QOE/QOS MAPPING MODELS QoE/QoS mapping models can be classified according to their inputs into three categories: 1. Black-box media-based models 2. Glass-box parameter-based models 3. Gray-box parameter-based models Mustufa Sir

- 5. 2. Glass-Box Parameter-Based QoS/QoE Mapping Models • A well-known offline glass-box parameter- based model, named E-Model, has been defined by the ITU-T. • E-Model aims at estimating QoE of voice calls transmitted over a planned transport infrastructure Mustufa Sir

- 7. 2. IP-ORIENTED PARAMETER-BASED QOS/QOE MAPPING MODELS • Network Layer QoE/QoS Mapping Models for Video Services where AL and VL refer respectively to audio and video packet loss rates, AJ and VJ represent respectively audio and video packet jitter (VJ), and RSSI is the received signal strength indicator.

- 9. • Application Layer QoE/QoS Mapping Models for Video Services where Lx refers to the start-up latency, that is, the waiting time before playing a video sequence, N is the number of quality switches that count the number of times the video bit rate is changed during a session, N is the number of rebuffering events, and T is the mean rebuffering time.
